    摘要: A system comprises a first operating environment and a second operating environment. The first and second operating environments exchange information in encrypted form using a shared encryption key (K3). The first and second operating environments cooperate to change said encryption key K3 using another shared encryption key (K4). The encryption key K4 is changed upon the encryption key K3 being changed.

    摘要: A system comprises storage and a basic input/output system (BIOS) stored in the storage and adapted to be executed by a processor. The BIOS has an associated setting. The system receives an encrypted value that comprises an encrypted hash of a request to alter at least one of the BIOS and the setting. A first key is used to encrypt the value. The processor uses a second key corresponding to the first key to authenticate said request.
