Abstract

Elliptic Curve Cryptography (ECC) is emerging as an attractive public-key cryptosystem for mobile/wireless environments. Compared to traditional cryptosystems like RSA, ECC offers equivalent security with smaller key sizes, which results in faster computations, lower power consumption, as well as memory and bandwidth savings. This is especially useful for mobile devices which are typically limited in terms of their CPU, power and network connectivity. However, the true impact of any public-key cryptosystem can only be evaluated in the context of a security protocol. This paper presents a first estimate of the performance improvements that can be expected in SSL (Secure Socket Layer), the dominant security protocol on the Web today, by adding ECC support.
