Abstract: Techniques for encrypting data using a key generated by a physical unclonable function (PUF) are described. An apparatus according to the present disclosure may include decoder circuitry to decode an instruction and generate a decoded instruction. The decoded instruction includes operands and an opcode. The opcode indicates that execution circuitry is to encrypt data using a key generated by a PUF. The apparatus may further include execution circuitry to execute the decoded instruction according to the opcode to encrypt the data to generate encrypted data using the key generated by the PUF.

Abstract: Techniques for encrypting data using a key generated by a physical unclonable function (PUF) or a virtual PUF key are described. An apparatus according to the present disclosure may include decoder circuitry to decode an instance of a single instruction having a field for an opcode to indicate that execution circuitry is to encrypt at least encrypt secret information from an input data structure with either a physical unclonable function (PUF) generated encryption key or a virtual PUF key, bind the wrapped secret information to an identified target, update the input data structure, generate a MAC over the updated data structure, store the MAC in the input data structure to generate a wrapped output data structure, store the wrapped output data structure having the encrypted secret information and an indication of the target;

Abstract: Techniques for memory assisted inline encryption/decryption are described. An example includes an encryption data structure engine to provide a key, data, and a tweak to the encryption/decryption engine, wherein the encryption data structure engine is to: read an index value from an encryption data structure lookup data structure entry using an address, the entry to include the index value and a guest page physical address (GPPA), retrieve, based on the index value, an entry from the encryption data structure, the entry to include a logical block address (LBA) base, a key identifier, and at least one GPPA in a sequence of GPPAs, generate a LBA using a position of the GPPA from the encryption data structure lookup data structure entry in the sequence of GPPAs, and retrieve a key based on the key identifier, wherein the encryption engine to encrypt data using the retrieved key, and the generated LBA.

Abstract: A method of handling a firmware update for a device is disclosed, comprising: determining a device to be in an updatable state; setting the device into an updating state after determining the updatable state; and after the device is in the updating state, writing a firmware update to memory for the device. After writing the firmware update, the device is switchable to a working state in which the device operates based on the firmware update.

Abstract: The present disclosure is directed to secure processing and display of protected content. The use of a trusted execution environment (TEE) to handle authentication and session key negotiation in accordance with a selected content protection protocol may reduce any trusted computing base (TCB) needed for such operations, and thereby present a smaller target for potential attackers. Techniques are presented in which a session key negotiated via such a TEE is securely provided to output circuitry such as a display controller, which may encrypt protected content that has been requested for viewing on a protocol-compliant display device communicatively coupled to a device comprising the TEE and/or the output circuitry. The output circuitry may then provide the encrypted protected content to the protocol-compliant display device, such as for compliant display of the protected content.
