    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 are described for providing low-overhead cryptographic memory isolation to mitigate attack vulnerabilities in a multi-user virtualized computing environment. Memory read and memory write operations for target data, each operation initiated via an instruction associated with a particular virtual machine (VM), include the generation and/or validation of a message authentication code that is based at least on a VM-specific cryptographic key and a physical memory address of the target data. Such operations may further include transmitting the generated message authentication code via a plurality of ancillary bits incorporated within a data line that includes the target data. In the event of a validation failure, one or more error codes may be generated and provided to distinct trust domain architecture entities based on an operating mode of the associated virtual machine.

    Abstract: In one example, a system for asymmetric device attestation includes a physically unclonable function (PUF) configured to generate a response to a challenge. A pseudo-random number generator generates a set of random numbers based on the response. A key generator determines co-prime numbers in the set of random numbers and generates a key pair using the co-prime numbers, wherein the public key is released to a manufacturer of the component for attestation of authenticity of the component. Through extending the PUF circuitry with a pseudo-random number generator, the present techniques are able to withstand unskilled and skilled hardware attacks, as the secret derived from the PUF is immune to extraction.
