Abstract
Systems, apparatuses and methods provide for technology that determines that first data associated with a first security domain is to be stored in a first permutated cache set, where the first permuted cache set is identified based on a permutation function that permutes at least one of a plurality of first cache indexes. The technology further determines that second data associated with a second security domain is to be stored in a second permutated cache set, where the second permuted cache set is identified based on the permutation function. The second permutated cache set may intersect the first permutated cache set at one data cache line to cause an eviction of first data associated with the first security domain from the one data cache line and bypass eviction of data associated with the first security domain from at least one other data cache line of the first permuted cache set.
