Increase IoT device security with the Microchip ATECC508A

In the last few weeks the technology news spotlight has been turned towards the Internet of Things, thanks to recent breaches of security – botnet attacks and the like. This should be a powerful reminder to all in the industry that security can no longer be considered optional, or an after-thought.

One solution to increasing data security in Internet of Things devices is with Microchip's new ATECC508A security co-processor - a small device which can be pre-loaded with cryptographic keys, keeping these keys securely stored within your embedded and IoT devices.

The ATECC508A can also function as a cryptographic co-processor, executing strong cryptographic algorithms without burdening the resources of the host microprocessor or microcontroller. It is well-suited for use in networked IoT devices in security-conscious applications - markets such as industrial control or SCADA networks, medical devices, utility metering and home automation.

Furthermore, the ATECC508A features a high-quality random number generator, entropy and seed sources, internal generation of secure unique keys and the ability to seamlessly accommodate various different kinds of provisioning workflows - where your product is initially set up with secure keys, in the most cost-effective manner depending on manufacturing volume.

These devices are compact, very low in cost, and require very little additional hardware integrated into your design. As with other CryptoAuthentication devices, the ATECCC508A delivers extremely low-power consumption, requires only one or two host microcontroller pins, operates over a wide voltage range - and has a tiny form factor, making it ideal for a variety of IoT applications that require longer battery life and compact form factors.

This slightly increased hardware cost may be easily compensated for by the reduced need for computational resources on the main microcontroller. The ATECCC508A device is compatible with any microprocessor or microcontroller including Atmel SMART and Atmel AVR devices.

The device provides secure hardware-based key storage based around elliptic-curve cryptography (ECC), and provides secure digital signature and mutual authentication capability through the use of Elliptic Curve Digital Signature Algorithm (ECDSA) techniques.

Secure key agreement, through Elliptic Curve Diffie-Hellman technology, is also provided. The combination of ECDH and ECDSA makes the ATECC508A a powerful security and cryptography platform that effectively provides three pillars of information security - confidentiality, data integrity, and authentication - when used with microcontroller systems that would otherwise be dependent on cryptographic algorithms such as AES running in their software.

Atmel/Microchip's CryptoAuthentication portfolio now includes two series of devices offering advanced Elliptic-Curve Cryptography capabilities. Because the new ATECC508A has ECDH and ECDSA built-in, it enables design engineers to provide a high assurance of confidentiality, data integrity and authentication in today's connected IoT devices.

The ATECC508A safeguards private keys, certificates and other sensitive security data to ensure authentication and protection against security threats such as physical tampering, cloning, RF and power analysis attacks. The compact device is integrated into your hardware alongside the host microprocessor, and it interfaces to the host over an I2C bus.

The chip features strong resistance against environmental and physical tampering, providing countermeasures against advanced intrusion techniques.

This security co-processor also simplifies the mutual authentication needed to connect networks of IoT devices to cloud ecosystems such as Amazon Web Services IoT, and it eliminates the complexity associated with software-centric security implementations.

Moving away from relatively complex, computing-intensive and less secure software-based security solutions does not come at a high cost, though. The device also provides dedicated hardware for cryptographic acceleration, so it can offload mathematically-intensive strong cryptology from the main microprocessor or microcontroller in the system, saving CPU resources.

This is particularly valuable in connected IoT devices employing low-power, low-cost microcontrollers, as it allows strong security capabilities to be maintained without the cost and power consumption of a more powerful processor.

To make prototyping and designing easier, Microchip provides the Zero Touch Secure Provisioning Kit for Amazon Web Services IoT. This kit allows you to seamlessly connect to the AWS IoT platform while maintaining strong security - complying with the AWS mutual authentication security model.

In an AWS-connected IoT installation, the host microprocessor runs an AWS Software Development Kit that integrates support for the ATECC508A, so the device - and the private keys and certificates that it stores - is automatically recognised by AWS IoT, and when the device connects to AWS mutual authentication and key provisioning is carried out automatically. This allows highly secure IoT node-to-cloud environments to be easily and quickly deployed, even with smaller-scale installations.

Thanks to Microchip’s new ATECC508A, an increased and useful level of security can be incorporated in your Internet-of-Things device. And here at the LX Group we have the systems in both hardware and software to make your IoT vision a success. We have end-to-end experience and demonstrated results in the entire process of IoT product development, and we’re ready to help bring your existing or new product ideas to life.

Espressif ESP32 – driving down the cost of the Internet of Things

The recently-finalised ESP32 is Espressif's successor to the popular ESP8266 wireless connectivity system-on-chip - taking the low-cost connected platform even further with a new combination Wi-Fi and Bluetooth SoC.

The ESP32 offers powerful processing capability, flexible wireless connectivity, and strong support for sensor and peripheral interfaces, while maintaining low power consumption and efficient sleep modes that make it well suited for battery-powered applications.

These features, along with its low cost, make the ESP32 particularly attractive for mobile devices, wearable electronics and Internet-of-Things technologies.

Interfacing the ESP32 with other microcontrollers in an existing design is possible, adding on Wi-Fi or Bluetooth wireless connectivity in a peripheral way, through its UART, I2C, SPI or SDIO interfaces - but if you want to start from scratch with a new design the power of the ESP32 really comes into its own as a standalone wireless connectivity and processing platform. It provides almost everything you need for a complete Internet-of-Things application in one low-cost, compact chip.

The ESP32 uses a similar Xtensa LX6 32-bit CPU to the ESP8266, but has moved up to two processor cores, each of which can run at up to 240 MHz. The platform includes 128kB of ROM and 520kB of SRAM, and support for external Flash memory up to 64Mb in size, for program and data storage.

The device has 36 GPIO pins, and the use of a crossbar matrix means that any GPIOs, serial interfaces, timers and ADCs can be assigned to whichever pins you need. 16 channels of 12-bit ADC inputs are included, along with a programmable internal voltage reference - a huge step up from the limited resolution of the single ADC input pin on the ESP8266.

Up to 16 PWM output pins are provided, along with two 8-bit true DAC outputs, and two I2S interfaces which can be used for digital audio output into an external DAC, for example in an embedded internet radio application.

Multiple SPI and I2C ports are also provided, along with analog preamplifiers, a Hall-effect sensor, a temperature sensor, capacitive touch keypad inputs, and a JTAG interface that can be used for debugging with OpenOCD.

As well as 802.11b/g/n 2.4GHz WiFi, the ESP32 radio architecture also includes Bluetooth 4.2 support, both Bluetooth Classic and Bluetooth Low Energy, making it an extremely versatile, flexible platform for many wireless connectivity and Internet-of-Things applications.

The RF stage includes its RF switches, baluns, power amplifier, LNA and filters all integrated on the IC, meaning that almost no external components are required for wireless connectivity. This keeps physical size of the layout down, reduces BOM cost, makes it easier to use pre-certified radio modules incorporating the ESP32 chip and antenna connector, and reduces the amount of specialist RF expertise you need to successfully incorporate the ESP32 into your design.

Hardware accelerators for AES and SSL/TLS are also provided, allowing strong security to be easily implemented in Internet-of-Things applications without burdening the processors with the cryptography required.

These SDKs and software tools continue to be under active development, with more bug fixes and enhancements every day, and even though things are very immature at this stage, this development is occurring openly, where feedback from users and other developers is encouraged.

Just as we've seen with the ESP8266, we are likely to see the development of many community-driven open source software tools to support the ESP32, such as an ESP32-ready port of the NodeMCU Lua interpreter and support in the Arduino IDE for programming the ESP32, using the popular and easy-to-learn Arduino language. (This open-source ESP32 extension for the Arduino development environment is already under active development.)

Many of the system, GPIO and wireless networking function calls in the ESP32 SDK are fully compatible with the ESP8266 API, so it's likely that many of these software tools will be ported across in the near future without too much difficulty.

Following the success of the ESP8266, Espressif has greatly enhanced its community engagement around the ESP32, putting much more effort into open support, comprehensive documentation, English-language datasheets and manuals - and engagement with the smaller-scale independent and "maker" communities of users. This also helps developers in the professional sphere as well.

Espressif provides the new ESP32 Software Development Kit, which they call the ESP32 "IoT Development Framework" (IDF) to distinguish it from previous SDKs, along with a suite of examples and documentation to allow users to easily get started with ESP32 software development. These resources include libraries, source files, example code, development toolchains, and everything else you need to get up and running.

With the possibility of such as low-cost and powerful microcontroller, you can imagine how excited the market is to receive the ESP32. And here at the LX Group we have the systems in both hardware and software to make your IoT vision a success.

Data buses simplified with the new I3C specification

The relatively new I3C specification, an extension of the popular Inter-Integrated-Circuit (I2C) serial bus for embedded systems, is actively under development and has recently reached the draft stage – with details available to the members of the MIPI Alliance for development and review.

I3C is being developed by the MIPI (Mobile Industry Processor Interface) Alliance, and it is specifically aimed at addressing future-proof interconnect needs in embedded mobile, Internet-of-Things and wearable computing devices that incorporate ever-greater numbers of advanced sensors and peripheral devices.

The MIPI I3C specification combines features from I2C and SPI into a new unified standard and scalable interface to connect many devices in embedded systems together - with minimal pin use, new capabilities, and improvements in power management and data rate.

The MIPI Sensor Working Group, consisting of many major system design and ASIC vendors, has been jointly defining the I3C specification, with the goal to re-use existing interfaces as much as possible while reducing pin count, providing in-band interrupts, reducing power use and engineering cost, as well as increasing bandwidth.

I3C builds new features onto the mature I2C standard such as a new high-data-rate mode which can support lots of data from sensors or other peripheral device – along with better support for relatively large networks of many devices connected to a host microcontroller.

Furthermore, I3C can compete with higher-bandwidth embedded serial interfaces like SPI, but still use only two wires like I2C does. The I3C standard is backwards compatible with I2C, so legacy devices with I2C interfaces can connect to the I3C bus, however new hardware (both on the peripheral and on the host controller side) is needed to take full advantage of the bandwidth and other benefits that I3C provides.

I3C offers higher speeds, greater power efficiency, reduced pin count compared to multi-device SPI networks, and support for relatively large sensor suites connected to a host microcontroller using only two wires but carrying ever-greater amounts of rich sensor data in wireless sensor network and IoT applications.

I3C was developed by MIPI's Sensor Working Group as a potential way to unify the serial bus landscape with a single, consistent interface that can handle any kind of device, allowing all kinds of sensors to be very easily integrated into embedded systems.

It aims to combine the simplicity and the low wire count of I2C with the high speed and power efficiency of SPI, to merge both these popular

standards together, and to add powerful new features such as in-band interrupt support with no need for extra interrupt wires, advanced power management and dynamic addressing of the different ICs on the bus. And I3C does all of this while largely maintaining backwards compatibility with existing I2C devices.

A typical smartphone today may contain up to a dozen sensors, and the widespread adoption and cost reduction of technologies like MEMS means that these sensors are producing much more complex, rich data.

Moving all this data back to the central controller is stretching the capabilities of today's familiar interfaces such as SPI or I2C, and this is the problem that I3C is primarily designed to address. I3C aims to incorporate and unify key attributes of I2C and SPI while improving the capabilities and performance of each approach with a comprehensive, scalable interface and architecture.

A typical system in use today may use a combination of I2C and SPI devices, with three wires for SPI, two wires for I2C, one further wire for each SPI device select line, plus an interrupt line for each peripheral device.

This complexity adds up quickly with modern sensor suites, and I3C aims to replace a dozen or more wires with just two wires, providing in-band interrupt capability without any need for dedicated interrupt lines wired back to the host device, reducing fragmentation between these different standards in the device market, freeing up pins on the host device, simplifying PCB engineering and making devices smaller, as well as offering speeds of up to 27 megabits per second.

I3C also includes multi-master support - this means it provides the ability for devices on the bus to request to take the master role, so the bus architecture is not limited to one single fixed master device and a number of slave devices.

Devices can be both master and slave, and direct "peer-to-peer" communication between I3C devices on the bus is possible without the master device needing to be involved in this exchange. I3C also introduces dynamic addressing, hot-joining and a uniform approach for advanced power management features such as sleep modes.

Devices on the bus can be powered on and off, and they don't have to be activated when the I3C bus is powered up. They can be added onto the bus later, or connected initially but not powered on, without any issues with loading down the bus.

This hot-joining capability, like with USB devices, allows the master device to assign a dynamic address to the slave device when it comes up on the bus, and has advantages for power efficiency when sensor and peripheral devices are turned off and on to save power, as well as allowing for removable, hot-swappable modules.

Dynamic address configuration means that the master device on the bus assigns each device a unique address, either when the bus is initialised or when a new device is connected to an already-configured I3C bus. Like the now-ubiquitous dynamic host configuration in IP networks, this automatic address configuration potentially makes it much easier to set up I3C hardware, removing conflicts between hardware devices with fixed addresses.

We look forward to the evolution that is the I3C data bus, and how it can be part of efficient Internet of Things devices. And if you are too, here at the LX Group we have the systems in both hardware and software to make your IoT vision a success.

Power Efficient LTE Wireless from Qualcomm for the Internet of Things

Qualcomm has recently announced the introduction of its new MDM9207-1 chipset, an LTE modem solution that is designed to support reliable, global cellular connectivity on modern LTE networks for a growing array of connected products and systems.

Their MDM9207-1 is purpose-built for Internet-of-Things applications, targeting growing IoT application areas such as smart metering, security, asset tracking, wearables and industrial automation.

Many of these applications require constantly available, reliable and power-efficient connections to Internet and cloud services that are mobile and ubiquitous, and LTE connectivity delivers this.

With category 1 LTE connectivity, the MDM9207-1 offers multi-mode and multi-band support for global compatibility and interoperability with legacy networks in countries where LTE deployment has been slower, as well as an on-board application processor and many other valuable features.

It offers device makers, system integrators and developers a mature modem platform that features industry-leading 3G/4G LTE multimode and multiband support, and it's designed to support connections on all major cellular networks worldwide.

Furthermore, LTE extends the communications range that devices are capable of, well beyond the limited range of Wi-Fi or Bluetooth to an effectively unlimited range - and this new chipset does this without the high power consumption of some older cellular modems.

Final device size is not forgotten, as the MDM9207-1 has advanced power saving features for devices that are persistently connected, as well as for those that require less frequent wake-up and communication with the network.

It features a powerful application processor capable of running applications under Linux, GPS positioning and location services, and advanced security and authentication features, all in a highly integrated package that reduces component count, bill-of-materials cost, design complexity, size and integration time.

The platform includes support for LTE Category 1, with up to 10 Mbps downlink and 5 Mbps uplink speeds, with LTE multimode or single-mode capability and dual or single receive, and all modern cellular standards are implemented, including LTE FDD, LTE TDD, DC-HSPA, GSM and TD-SCDMA.

There is also support for voice communication to be integrated, via VoLTE (Voice over LTE) or CSFB (Circuit Switched Fall Back). Qualcomm is designing its IoT cellular products to support many LTE standards across worldwide markets, which is a challenge, since countries such as China typically use different LTE standards than the ones used in the U.S. and Europe, for example.

The MDM9207-1 chipset features a 1.2 GHz ARM Cortex M7 application processor built in - capable of running Linux to host user applications, providing powerful application capabilities without any need to add extra hardware or BOM cost.

The platform also features a power-save mode that can enable up to 10 years of battery life from a pair of AA batteries (in certain embedded sensor applications), advanced hardware and software security features built-in, and integrated GPS/Glonass support. Pre-integrated support for easily adding both Bluetooth Low Energy 4.1 and Qualcomm's VIVE 802.11ac Wi-Fi is also provided.

This solution is designed to be flexible, scalable, cost-optimized and energy efficient - purpose-built to meet the needs of IoT applications. It features scalable, reusable software across different chipset platforms, reducing design complexity, cost and time to market for your IoT solution.

Device makers and developers can reduce their time-to-market for IoT products, as well as reducing development costs, by utilizing a single software code base across all implementations of this flexible chipset family. The same core modem technology is already deployed in millions of Qualcomm's Snapdragon chipsets around the world, so unifying around a single, consistent code base has a lot of value.

The MDM9207-1 is designed to minimize the need for additional discrete processors or microcontrollers, cellular radio or GPS chips, replacing all these separate components with one feature-packed integrated chipset. This reduces the bill-of-materials cost, makes manufacturing easier - and makes finished devices smaller.

In time, it's likely that we'll see complete cellular sensor network solutions where a suite of sensors are integrated alongside the single-chip MDM9207-1 providing cellular connectivity and an application processor - possibly even, in time, the integration of the entire sensor node onto a single chip.

Many cellular network operators around the world are already in the process of phasing out their 2G networks to make room for LTE, but LTE is here for the "long run", and embedded devices built with LTE cellular connectivity are likely to remain working, with a network provider, many years down the track.

While LTE networks are already relatively mature in North America, parts of Asia, and Europe, the multimode capability of the MDM9207-1 platform is designed to allow customers to seamlessly and cost-effectively connect their devices to both LTE as well as legacy networks. This is particularly important in Australia, and in many other countries, where LTE network support may not be as widespread or mature, but future-proof LTE products and infrastructure can be rolled out now and used right now on 3G/4G networks.
