A growing need for ultra-high-speed data transfers has motivated continued improvements in the transmission speeds of the physical network layer. As researchers develop protocols and software to operate over such networks, they often fail to account for security. The processing power required to encrypt or sign packets of data can significantly decrease transfer rates, and thus security is often sacrificed for throughput. Emerging multicore processors provide a higher ratio of CPUs to network interfaces and can, in principle, be used to accelerate encrypted transfers by applying multiple processing and network resources to a single transfer.
