This work presents a high performance heterogeneous parallel method for encryption using GPUs. Our heterogeneous design executes most of the encryption processes on the GPU and partially on CPU. Aside from the AES 16 Byte block size, our parallel AES CTR algorithm divides work in small logical data blocks. We have devised a novel latency hiding scheme that suits the parallel CTR encryption mode by speculatively encrypting and caching data blocks ahead of time on the GPU. The algorithm also… CONTINUE READING
