Abstract
A microprocessor includes random cache line refill ordering to lessen side channel leakage in a cache line and thus thwart cryptanalysis attacks such as timing attacks, power analysis attacks, and probe attacks. A random sequence generator is used to randomize the order in which memory locations are read when filling a cache line.
