Designing Integrated Accelerator for Stream Ciphers With Structural Similarities
Till date, the basic idea for implementing stream ciphers has been confined to individual standalone designs. In this paper, the authors introduce the notion of integrated implementation of multiple stream ciphers within a single architecture, where the goal is to achieve area and throughput efficiency by exploiting the structural similarities of the ciphers at an algorithmic level. They present two case studies to support their idea. First, they propose the merger of SNOW 3G and ZUC stream ciphers, which constitute a part of the 3GPP LTE-Advanced security suite. They propose HiPAcc-LTE, a high performance integrated design that combines the two ciphers in hardware, based on their structural similarities.
