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: 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: Disclosed embodiments relate to encoded inline capabilities. In one example, a system includes a trusted execution environment (TEE) to partition an address space within a memory into a plurality of compartments each associated with code to execute a function, the TEE further to assign a message object in a heap to each compartment, receive a request from a first compartment to send a message block to a specified destination compartment, respond to the request by authenticating the request, generating a corresponding encoded capability, conveying the encoded capability to the destination compartment, and scheduling the destination compartment to respond to the request, and subsequently, respond to a check capability request from the destination compartment by checking the encoded capability and, when the check passes, providing a memory address to access the message block, and, otherwise, generating a fault, wherein each compartment is isolated from other compartments.

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;
