Crypto-authentication Device Adds Hardware-based Security To IoT Designs


Microchip has created the ATECC608A CryptoAuthentication device, a secure element that allows developers to add hardware-based security to their designs. The firm has also established a Security Design Partner Program for connecting developers with third-party partners that can enhance and expedite secure designs.

The ATECC608A can be used in Internet of Things (IoT) applications including home automation, industrial networking, medical, as well as accessories and consumables authentication and more.

By keeping a device’s private keys isolated from the system in a secured area, coupled with its industry-leading cryptography practices, the ATECC608A provides a high level of security that can be used in nearly any type of design, according to Microchip.

“From remote cyber-attacks to the creation of counterfeit products, security threats are wide-spread and affect all industries. When carried out, these threats can translate into substantial losses in recovery costs, service revenue and perhaps most significantly, in brand equity”, Microchip noted in the Press release.


The Federal Information Processing Standard (FIPS)-compliant Random Number Generator (RNG) generates unique keys compliant with the latest requirements from the National Institute of Standards and Technology (NIST), providing an easier path to a whole-system FIPS certification.

New commands facilitate the signature validation and digest computation of the host microcontroller (MCU) firmware for systems with small MCUs, such as an ARM Cortex-M0+, as well as for more robust embedded systems.

The AES-128 engine also makes security deployments for LoRa infrastructures possible by enabling authentication of trusted nodes within a network.

In addition, the hardware-based integrated Elliptical Curve Cryptography (ECC) algorithms create smaller keys and establishes a certificate-based root of trust more quickly and securely than other implementation approaches that rely on legacy methods.

The chip comes with anti-tampering techniques to protect keys from physical attacks and attempted intrusions after deployment. These techniques allow the system to preserve a secured and trusted identity, the company said.

“Security is essential for today’s connected applications, especially for those spanning from hardware to the cloud,” said Nuri Dagdeviren, vice president of Microchip’s Secure Products Group. “This is why Microchip offers both proven hardware security solutions and an unprecedented level of partnership with leading cloud providers, giving our customers all the building blocks to create secure solutions that protect their IP, brand value and revenue streams.”

Those designing a hardware security solution with the new chip are also given access to Microchip’s Security Design Partner Programme , including Amazon Web Services (AWS) and Google Cloud Platform, providing them complementary cloud-driven security models and infrastructure.

For rapid prototyping of secure solutions, designers can use the new CryptoAuth Xplained Pro evaluation and development kit (ATCryptoAuth-XPRO-B) which is an add-on board, compatible with any Microchip Xplained or XplainedPro evaluation boards.

The ATECC608A is available in 10,000 unit quantities. The ATCryptoAuth-XPRO-B add-on development board is also available.
