Microchip packages hardware security IC with 3rd-party & cloud services
Hardware is in the form of the ATECC608A CryptoAuthentication device, a secure element that allows developers to add hardware-based security to their designs, to create, protect and authenticate a device’s unique and trusted identity. By keeping a device’s private keys isolated from the system in a secured area, coupled with advanced cryptography practices, the chip provides a high level of security that can be used in nearly any type of design. Features include;
– Federal Information Processing Standard (FIPS)-compliant Random Number Generator (RNG) that 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.
– Boot validation capabilities for small systems: new commands facilitate the signature validation and digest computation of the host microcontroller (MCU) firmware, including systems with small MCUs.
– Trusted authentication for LoRa nodes: the AES-128 engine also makes security deployments for LoRa infrastructures possible by enabling authentication of trusted nodes within a network.
– Hardware-based integrated Elliptical Curve Cryptography (ECC) algorithms create smaller keys and establish a certificate-based root of trust more quickly and securely than other implementation approaches that rely on legacy methods.
– Anti-tampering techniques protect keys from physical attacks and attempted intrusions after deployment. These techniques allow the system to preserve a secured and trusted identity.
– Trusted in-manufacturing provisioning: companies can use Microchip’s secured manufacturing facilities to safely provision their keys and certificates, eliminating the risk of exposure during manufacturing.
In addition to providing hardware security solutions, OEMs have access to Microchip’s Security Design Partner Programme including Amazon Web Services (AWS) and Google Cloud Platform, providing complementary cloud-driven security models and infrastructure.
The combination, Microchip says, enables an easier path to a whole-system FIPS certification.
For rapid prototyping of secure solutions designers can use the CryptoAuth Xplained Pro evaluation and development kit in addition to the ATCryptoAuth-XPRO-B add-on board, priced at $10, which is compatible with any Microchip Xplained or XplainedPro evaluation board.
