Abstract: Methods and apparatus relating to an efficient implementation of ZUC authentication are described. In one embodiment, a processor computes a tag update, based at least in part on stored data, for an authentication operation. The tag update is computed by replacing a ‘for’ loop with a carry-less multiply operation. Other embodiments are also claimed and disclosed.

Abstract: Some aspects of the present disclosure relate to an apparatus comprising interface circuitry and processor circuitry to write data bits to a memory, by applying a diffusion function on the data bits to calculate diffused data bits, calculating error correcting code (ECC) bits based on the data bits or based on the diffused data bits, applying a diffusion function on the ECC bits to calculate diffused ECC bits, storing the diffused ECC bits in an ECC portion of the memory, and storing the data bits or the diffused data bits in a data portion of the memory.

Abstract: The technology described herein includes a first plurality of bijection diffusion function circuits to diffuse data bits into diffused data bits and store the diffused data bits into a memory; an error correcting code (ECC) generation circuit to generate ECC bits for the data bits; and a second plurality of bijection diffusion function circuits to diffuse the ECC bits into diffused ECC bits and store the diffused ECC bits into the memory.

Abstract: Various examples relate to apparatuses, methods, and computer programs for executing an executable, and to a method for distributing software or firmware. An apparatus for executing an executable comprises interface circuitry, machine-readable instructions, and processing circuitry for executing the machine-readable instructions to identify, for the executable, a trigger to activate or deactivate a noise injection mode during execution of the executable, the noise injection mode being suitable for introducing noise during execution of the executable, and activate or deactivate the noise injection mode based on the identified trigger.

Abstract: Examples described herein relate to executing, on at least one processor, at least one Advanced Encryption Standard (AES) instruction, having an operation code (opcode), on operands, wherein execution of the at least one AES instruction generates an S1 box and/or S2 box of initialization and keystream generation for a SNOW3 cipher operation.

Abstract: A method comprises discovering, in a controller device, one or more target devices that are in a pairing mode, generating, in the controller device, a first signal comprising a pattern, transmitting, from the controller device to a first remote device, the first signal comprising the pattern, receiving, in the controller device, a second signal from a second remote device, the second signal comprising a authentication code, and authenticating the one or more target devices when the first authentication signal and the second authentication signal match.
