Abstract: Cache-based side-channel attacks have raised serious security concerns in the contemporary cache architectures. To mitigate these attacks, various cache architectures have been proposed that rely on cache partitioning and random memory-to-cache mapping based methods. Unfortunately, these cache methods are not adopted by the mainstream processors because of unfavorable security and performance trade-off. In literature, the Indirect-Eviction Cache (IE-Cache), a random memory-to-cache mapping based cache architecture, has shown high security and faster execution time by introducing the principles of multi-indexing and relocating the cache lines. However, IE-Cache requires relocation of cache lines that result in high energy consumption along with security. In this paper, we alleviate the energy consumption issue in IE-Cache by introducing a pointer-based mapping between tag and data store, which we call PIE-Cache (Pointer-based IE-Cache). This enables relocation of pointers in the tag-s tore without relocating a large cache line in the data-store, yielding low energy consumption compared to IE-Cache. We have developed the PIE-Cache model in the gem5 simulator to evaluate the energy consumption with Micro-benchmark. The results show that the energy consumption of 1MB PIE-Cache with 4 ways and 3 levels is 20% less compared to IE-Cache with the same capacity, ways and levels over Micro-benchmark. Moreover, we have performed the security evaluation of PIE-Cache in the same way as proposed in IE-Cache study to compare the learning time of eviction sets. These results show that the complexity of learning eviction sets is similar to IE-Cache. (More)
