I am working on a project that uses the TPM to do remote attestation between different machines.
Currently, I am trying to run our software on a system that uses an Atmel TPM device. My problem is that I can't find the parent certificate for the Endorsement Key of the device anywhere.
The issuer's distinguished name for the extracted EK is: "C=US, ST=Colorado, L=Colorado Springs, O=Atmel, CN=Atmel Signing Module 22".
Can someone please provide me the Atmel CA's certificate, preferably with a way to establish a trust chain (signed by a known CA or downloadable over https)?
