There has been a lot of interest in recent years in the problems faced by cryptosystems due to side channel attacks. Algorithms for elliptic curve point scalar multiplication such as the double and add method are prone to such attacks. By making use of special addition chains, it is possible to implement a simple power analysis (SPA) resistant cryptosystem.(More)

Hash functions play an important role in modern cryptography. This paper investigates optimisation techniques that have recently been proposed in the literature. A new VLSI architecture for the SHA-256 and SHA-512 hash functions is presented, which combines two popular hardware optimisation techniques, namely pipelining and unrolling. The SHA processors are(More)
Elliptic curve cryptosystems (ECC) have become popular in recent years due to their smaller key sizes than traditional public key schemes such as RSA. However the gap between the sizes of these systems is increasing as security requirements become more demanding due to cryptanalytic advances. At current security levels of 80 bits, the corresponding key(More)
Modular inversion is a critical operation in elliptic curve cryptosystems (ECC). This paper presents a hardware optimised modular inversion algorithm targeted towards an FPGA implementation. It exploits the underlying structure of the device, leading to a fast and efficient design. Arithmetic is performed in the Montgomery domain, which allows an inversion(More)
