METHOD AND APPARATUS FOR MIGRATING A VIRTUAL TPM INSTANCE AND PRESERVING UNIQUENESS AND COMPLETENESS OF THE INSTANCE |
摘要 |
A migration scheme for virtualized Trusted Platform Modules is presented. The procedure is capable of securely migrating an instance of a virtual Trusted Platform Module from one physical platform to another. A virtual Trusted Platform Module instance's state is downloaded from a source virtual Trusted Platform Module and all its state information is encrypted using a hybrid of public and symmetric key cryptography. The encrypted state is transferred to the target physical platform, decrypted and the state of the virtual Trusted Platform Module instance is rebuilt.
