Abstract

Various technologies described herein pertain to a computing device that includes secure hardware (e.g., a TPM, a secure processor of a processing platform, protected memory that includes a software-based TPM, etc.). The secure hardware includes a shared secret, which is shared by the secure hardware and a server computing system. The shared secret is provisioned by the server computing system or a provisioning computing system of a party affiliated with the server computing system. The secure hardware further includes a cryptographic engine that can execute a cryptographic algorithm using the shared secret or a key generated from the shared secret. The cryptographic engine can execute the cryptographic algorithm to perform encryption, decryption, authentication, and/or attestation.
