Abstract

Unlike SET (secure electronic transaction) protocol. We propose an ASEP (advanced secure electronic payment) protocol, which uses ECC (elliptic curve cryptosystem with F/sub 2/ not F/sub p/) [N. Koblitz, (1987), V. S Miler, (1986), G. Harper et al., (1993)], SHA (secure hash algorithm) and 3BC (block byte bit cipher) instead of RSA and DES. To improve the strength of encryption and the speed of processing, the public key and the private key of ECC are used in SBC [I. S. Cho (2002)] algorithm, which generates session keys for the data encryption. In particular, when ECC is combined with SBC, the strength of security is improved significantly. As the process of the digital envelope used in the existing SET protocol is removed by the SBC algorithm, the processing time is substantially reduced. In addition, the use of multiple signatures has some advantages of reducing the size of transmission data as an intermediate payment agent and avoiding the danger of eavesdropping of private keys.
