TCG launches initiative to develop “world’s tiniest TPM”
Summary
As IoT adoption continues to grow, a rising number of devices are so small that the inclusion of a full TPM chip might be impractical due to factors such as cost, space and power. TCG’s new Measurement and Attestation RootS (MARS) Subgroup has been formed to develop specifications that will enable manufacturers to build compliant chips with very little overhead for them and their customers. In turn, this will allow greater reach of trusted computing technologies over a wider set of devices and use cases.” The first prototype for such a TPM (known as Radicle) was exhibited during TCG’s members’ meeting held in Warsaw, Poland, this week during the inaugural session of the MARS Subgroup. The team also agreed on the scope of its work, which will focus on the hardware requirements necessary to control and operate the primitives supporting the RTS and RTR, and the software API to access them. A number of TCG’s other ongoing projects were also progressed during the members’ meeting, including work on specifications for secure software and firmware updates for embedded systems.
