Secure element transcript attestation

[damip]

Hello,

I currently use the SE050 and I would like to attest a digest of the history of all host-chip communications since the start of the session in order to reduce trust requirements in the host.

I understand that the SE050 does not have this capability, and I am looking for alternatives that might allow this.

As a fallback, I found that the SE051P allows custom java card applets to be installed but I don't know what would be the exact process to build a prototype.

Thank you for your help.

Hi @damip 

Thanks for your post

The SE05x family does not have the capability to get history of the host-chip communication, this could be accomplished in the host but is up to your own implementation. 

For detail information about custom applets pf the SE051 please contact your local NXP representative.
