Secure Multiparty Electronic Payments Using ECC Algorithm: A Comparative Study

Abstract

This paper is an attempt at the detailed study of Cryptography algorithm. In resource constrained system, Elliptic Curve Cryptography is a promising alternative for public algorithms, because it provides similar level of security with proposed shorter keys than conventional integer based public key algorithm. ECC over binary field is taken up with special interest because the operation in binary filed operation, are thought to be more in space and efficient in time. However, ECC's software implementation, on binary field are slow, Specially on low end processors, which are used in small computing devices such as sensors node, mobile phone, etc. This proposed paper, studied the Cryptography algorithms and software implementation of ECC. Firstly, while implementing ECC with software, for example byte size may affect the choice of algorithm some architectural parameters has been examined. Also, identification of software for low-end processors has been done. In addition, the proposed paper has implemented ECC algorithm in Multiparty Electronic transaction.
