https://en.wikipedia.org/wiki/Trusted_execution_environment#Implementations Most ARM chips have TrustZone or some other TEE. Most Intel systems have a Mangement Engine. Most AMD systems have a Platform Security Processor. There are open source implementations of TEE, like OP-TEE. TEEs protect 'untrusted' software stacks (Windows, Linux, Android, etc.). It can be helpful for security, and may also be misused by attackers to abuse security and privacy. It is 'notorious' if you want to reconfigure a system in a way that the vendor would consider something more a security attack than a normal use case of a consumer. :-( _______________________________________________ Replicant mailing list Replicant@lists.osuosl.org http://lists.osuosl.org/mailman/listinfo/replicant
