Abstract: A processor employs a security module to manage authentication and encryption keys for the processor. The security module can authenticate itself to other processing systems, such as processing systems providing software to be executed at the processor, can generate keys for encrypting address spaces for the provided software, and can securely import and export information at the encrypted address spaces to and from the processing system. By using a security module that is separate from the processor cores of the processor to perform these security operations, the processing system allows software executing on the processor cores to manage operations based on the authentication and encryption keys without being able to read the keys themselves, thereby preventing unauthorized access by malicious software to the keys.
