Recently, a new lightweight block cipher, SKINNY, has been proposed by Beierle et al. in Annual Cryptology Conference 2016. This paper presents an area-efficient FPGA implementation of SKINNY block cipher. In this paper, a new column-serial structure is proposed to speed up SKINNY without compromising its area cost, and the implementation of SKINNY S-box is optimized by utilizing FPGA embedded dual-port...
In this paper, we propose a novel high-speed and SPA-resistant architecture for elliptic curve cryptography (ECC) point multiplication. A new Karatsuba-Ofman based pipelined multiplier is proposed to lower the latency, and an improved comb point multiplication method is employed to reduce the clock cycles and to resist simple power analysis (SPA). The proposed ECC architecture has been implemented...
