ST: drop-in solutions for IoT security

STMicroelectronics and Security Platform are bringing robust, efficient, and easy-to-use security solutions to IoT devices. ST’s STSAFE-TPM is a Trusted Platform Module that provides secure storage for data such as cryptographic keys needed to authenticate the system, using proven techniques such as anti-tamper, memory protection, and data-watching prevention. It meets industry-recognized security standards including Trusted Computing Group TPM 1.2 and TPM 2.0 protection profiles, IT-security Common Criteria Level 4+ (CC EAL4+) certification, and US Federal Information Processing Standard (FIPS) 140-2.

Using its Axio-OS secure operating system and Axio-RA remote-attestation verification solution, Security Platform checks for breaches of integrity by verifying the hash information of the device from a separate server. Together, these software modules also provide anti-cloning and anti-forgery protection, and process device authentication, message signing, and security update using only the appropriate signing code.

While this collaboration will deliver a pre-integrated, ready-to-use solution, it builds on the existing independent STSAFE-TPM ICs and Axio-OS and Axio-RA software the companies are already marketing and can help customers tie together. In these instances, Security Platform can supply Axio-OS and Axio-RA with a developer kit comprising a board and chipset to aid integration.

STSAFE-TPMs are available within the larger STSAFE family of ICs from ST, which are tailored to support platform integrity, authentication, secure storage and other cryptographic services in various classes of connected devices from small IoT devices to industrial or consumer products, and desktop computers.
