Method and system for protecting data keys in trusted computing

Abstract:

One embodiment described herein provides a system and method for facilitating user access to encryption keys stored within a hardware module. During operation, a server coupled to the hardware module receives a key request from the user, the key request comprising a user identifier and a key identifier. The server receives a voice message from the user, extracts voice features from a voiceprint associated with the received voice message, looks up voice features stored within the hardware module based on the user identifier, and compares the extracted voice features with the voice features stored within the hardware module. In response to the extracted voice features matching the stored voice features, the server retrieves from the hardware module an encryption key based on the user identifier and the key identifier.
