Design on Mobile Secure Electronic Transaction Protocol with Component Based Development

Abstract

Unlike SET(Secure Electronic Transaction) protocol. This paper proposes an MSET(Mobile Secure Electronic Transaction) protocol, which consists of ECC (Elliptic Curve Cryptosystem)[1, 2, 3], SHA(Secure Hash Algorithm) and 3BC(Block Byte Bit Cipher). It uses ECC(F2m not Fp) and 3BC instead of RSA and DES respectively. To improve the strength of encryption and the speed of processing, the public key and the private key of ECC are used in 3BC [5, 6] algorithm, which generates session keys for the data encryption. In particular, when ECC is combined with 3BC, the strength of security is improved significantly. As the process of the digital envelope used in the existing SET protocol is removed by the 3BC algorithm in this paper, the processing time can be reduced significantly. In addition, the use of multiple signature has some advantages of reducing the size of transmission data as an intermediate payment agent and avoiding the danger of eavesdropping of private keys. Finally, the object component technique in this paper can be used for encryption standardization and reusability.
