WebFeb 19, 2024 · The advent of CUDA-enabled GPU makes it possible to provide cloud applications with high-performance data security services. Unfortunately, recent studies have shown that GPU-based applications are also susceptible to side-channel attacks. These published work studied the side-channel vulnerabilities of GPU-based AES … WebNote that, even though standard non-bitsliced AES only processes one block of data at a time, I've included a block number at the top row of the diagram. This becomes relevant when comparing this standard packing order with the internal order used by Käsper and Schwabe, since their bitsliced AES implementation processes 8 blocks at the same time.
