ABSTRACT:
In one embodiment, a platform comprises a processor, an input/output control hub (ICH), and a trusted platform module (TPM). Coupled to the ICH, the TPM comprises an internal memory, and an asymmetric key generation unit. The symmetric key generation unit produces an ephemeral asymmetric key pair including an ephemeral asymmetric public key and an ephemeral asymmetric private key. Both the ephemeral asymmetric public key and the ephemeral asymmetric private key are used for encryption and decryption operations during a single communications session.
