Elliptic Curve Cryptography
Dr Michael Ganley, Head of Consultancy & Security Analysis, Zaxus Ltd, UK

Technical Stream - Friday 3 November 2000

Much of the security of e-commerce/m-commerce is based on digital signatures, normally computed using the RSA algorithm. An alternative approach uses the relatively new idea of elliptic curve cryptography (ECC), which seems to have advantages over RSA, especially when memory and processing power are limited (e.g., a smart card). This talk looks at the ideas behind ECC and provides an objective view of the benefits and disbenefits of ECC v RSA.
