Multiplication Based Elliptic Curve Encryption Scheme With Optimized Scalar Multiplication (MECES)

Elliptic Curve Cryptography (ECC) fits well for an efficient and secure encryption scheme. It is efficient than the ubiquitous RSA based schemes because ECC utilizes smaller key sizes for equivalent security. This feature of ECC enables it to be applied to Wireless networks where there are constraints related to memory and computational power. The goal of this research is to develop an efficient method for Scalar Multiplication and to develop simple and efficient encryption scheme. In this paper we have compared the security of Elliptic curve AES (ECAES) with the Encryption scheme proposed by us. A comparative study of ECC with RSA is made in terms of key size, computational power, size of data files and encrypted files.
