Technology distributor Avnet released on Monday an add-on module and reference design for its MicroZed Industrial IoT Kit, bringing Trusted Platform Module (TPM) security capabilities for platform integrity, remote attestation and cryptographic services often required by Industrial Internet of Things (IIoT) applications, implemented in a hardware root of trust for maximum security.
The Avnet-designed Infineon TPM V1.2 Peripheral Module is based on the OPTIGA TPM SLB9670 security solution from Infineon Technologies AG and connects to the Zynq-7000 All Programmable SoC from Xilinx Inc., which is included on Avnet’s MicroZed System-on-Module (SOM).
“In working with Xilinx and Infineon, Avnet has provided our design customers with an improved security capability for our solutions based on the Xilinx Zynq architecture,” said Ron Wright, technical marketing manager, Avnet Electronics Marketing. “With this low-cost Pmod, designers can easily explore a range of security options often required for factory automation, smart cities, smart grid and health care applications.”
The Infineon TPM add-on module, along with the downloadable reference design, enable measured boot functionality for the Avnet MicroZed SOM. The system also supports additional use cases such as device identity, secure storage, secure communications and secure firmware upgrade.
The TPM Pmod features Infineon’s OPTIGA™TPM SLB9670 which is compliant to the Trusted Computing Group (TCG) TPM 1.2 specification and connects to Zynq through a SPI interface. This Pmod, along with the downloadable reference design, enables measured boot functionality for the Avnet MicroZed Industrial IoT Starter Kit, featuring the Xilinx Zynq 7Z010 running WindRiver’s Pulsar Linux operating system.
The system also supports additional use cases such as Device Identity, Secure Storage, Secure Communications, and Secure Firmware Upgrade. When these capabilities are coupled with Zynq’s secure boot (hardware root of trust) feature, developers have the security foundation required for the IIoT.
“The addition of the Infineon Trusted Platform Module brings new levels of cybersecurity to the Industrial IoT Starter kit from Avnet. Utilizing the combination of Infineon’s TPM and Zynq’s Programmable SoC multi-layered security features, developers can rapidly realize a high degree of trustworthiness for their Industrial IoT platform when connecting from edge to cloud,” said Dan Isaacs, director of Industrial IoT ecosystem strategy and market development, Xilinx.
“Making our OPTIGA TPM available to customers as a peripheral module with a supporting reference design should make integration into new and existing designs much easier,” said Joerg Borchert, vice president of the chip card and security division, Infineon Technologies Americas Corp. “The TPM provides the higher level of security needed to protect network-connected systems against the flood of attacks they face every day.”
The Infineon TPM V1.2 Peripheral Module is now available from Avnet Electronics Marketing for US$29.95.
