Groundbreaking work to assure cybersecurity in the Internet of Things (IoT) era has been initiated, as the Trusted Computing Group (TCG) launched a new project to create the "world's tiniest Trusted Platform Module (TPM)."

Many manufacturers want to build devices that include Roots of Trust for Measurement (RTM), Storage (RTS) and Reporting (RTR) so that these devices can work securely within the TCG Measurement and Attestation framework. Today, TPM chips are used to implement the RTS and RTR in a highly secure manner.

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 a nutshell, we want to specify what the tiniest TPM needs to be so it can be integrated directly within the host chip," said Tom Brostrom, Chair of the MARS Subgroup. "This will ensure that devices that aren't big enough to integrate a separate TPM will still be able to retain the required RTS/RTR capabilities. 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 during the inaugural session of the MARS Subgroup. The team also agreed on the scope of its...
