Abstract: Examples include techniques to mitigate or prevent cache-based side-channel attacks to a cache. Examples include use of assigned class of service (COS) assigned to cores of a process to determine whether to notify an OS of a potential malicious application attempting to access a cache line cached to a processor cache. Examples also include marking pages in an application memory address space of a processor cache as unflushable to prevent a potentially malicious application from accessing sensitive data loaded to the application memory address space of the processor cache.

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: Examples include techniques to manage cache resource allocations associated with one or more cache class of service (CLOS) assignments for a processor cache. Examples include flushing portions of an allocated cache resource responsive to reassignments of CLOS.
