    Abstract: Memory scanning methods and apparatus are disclosed. An example apparatus includes a walker to traverse a paging structure of an address translation system; a bit analyzer to determine whether a bit associated with an entry of the paging structure is indicative of the entry being recently accessed; an address identifier to, when the bit analyzer determines that the bit associated with the entry of the paging structure is indicative of the entry being recently accessed, determine an address associated with the entry; and an outputter to provide the determined address to a memory scanner.

    Abstract: A processor is described that includes one or more processing cores. The processor includes a memory controller to interface with a system memory having a protected region and a non protected region. The processor includes a protection engine to protect against active and passive attacks. The processor includes an encryption/decryption engine to protect against passive attacks. The protection engine includes bridge circuitry coupled between the memory controller and the one or more processing cores. The bridge circuitry is also coupled to the protection engine and the encryption/decryption engine. The bridge circuitry is to route first requests directed to the protected region to the protection engine and to route second requests directed to the non protected region to the encryption/decryption engine.

    Abstract: A method, device, and system are disclosed. In one embodiment the method includes receiving measured health information from a client on a key distribution server. Once the measured health information is received the server is capable of validating the measured health information to see if it is authentic. The server is also capable of sending a session key to the client when the measured health information is validated. When the client receives the session key, the client is capable of initiating an encrypted and authenticated connection with an application server in the domain using the session key.
