New TPM Chip For Secured Authentication in Computing Environment


According to the press release, Infineon has announced the launch of OPTIGA TPM (Trusted Platform Module) for information security. TPM is basically a computer chip (microcontroller) that can securely store artifacts used to authenticate the platform i.e. PC or laptop. These artifacts can include passwords, certificates, or encryption keys. A TPM can also be used to store platform measurements that help ensure that the platform remains trustworthy. Authentication (ensuring that the platform can prove that it is what it claims to be) and attestation (a process helping to prove that a platform is trustworthy and has not been breached) are necessary steps to ensure safer computing in all environments.

Referring to the press release, “The OPTIGA TPM family provides hardware based security for system applications across industrial, embedded, mobile or tablets as well as traditional computing environments. The newly certified OPTIGA TPM 1.2 with SPI bus is the first of a next-generation of TPMs developed to meet future market requirements. The chip is based on Infineon’s security crypto controller and SOLID FLASH embedded memory. It also supports the use of TPMs in an even wider area such as industrial computing and embedded systems that are increasingly connected like IoT gateways, routers or even surveillance cameras. These applications may benefit, in particular, from an optimised interface with high performance.”

The features of TPM as highlighted below:

  • TCG TPM 1.2/2.0 compliant
  • Operating temperature range: -20°C to +85°C and wide temperature range  -40°C to +85°C
  • Optimized for battery operated devices: low standby power consumption (typ. 150µA) and sleep mode
  • Meeting Intel TXT, Microsoft Windows and Google Chromebook certification criteria for successful platform qualification
  • True Random Number Generator (TRNG)
  • Full personalization with Endorsement Key (EK) and EK certificate
  • Tick counter with tamper detection
  • NV storage space for keys and user defined data
  • Supports the TIS 1.3 interface specification
