SMS4 is widely used in the Chinese National Standard for Wireless LAN WAPI (Wired Authentication and Privacy Infrastructure), and in WLAN WAPI, low-cost and efficient cryptography algorithm implementation is necessary and challenging. This paper proposes an ultra-compact IP core architecture, where the input data is processed in bytes. The proposed architecture further reduces its hardware consump...Show More
Montgomery algorithm is the most common mechanism for implementing modular multiplication. This work proposes a new systolic architecture to perform high radix Montgomery algorithm on modern FPGA, which is rich in dedicated hardcore multiplier resources, and the new architecture is suitable to be used in public key coprocessors. In the modern FPGA application design, using dedicated hardcore in FP...Show More
SNOW 3G and ZUC are both the heart of secure algorithm sets in 3GPP LTE-Advanced, which is the potential candidate for 4G mobile broadband communication standard. In this paper, we optimize the implementation of the SNOW 3G and ZUC on FPGA, and also evaluate their performance. Our implementation of SNOW 3G reaches a little higher throughput than that of the best commercial IP core. Our optimized i...Show More
In this paper we propose a new hardware architecture of modular exponentiation, which is based on the optimized Montgomery multiplication. At CHES 1999, Tenca introduced a new architecture for implementing the Montgomery multiplication which was later improved by Huang et al. at PKC 2008. In this paper we improve the architecture of Huang and the improved one occupies less hardware resource, at th...Show More
