Secure Electronic Transactions via Cryptography Techniques

In recent years, many proposals for electronic payments via open network have been emerged. One of them is Secured Electronic Transaction (SET) protocol advertised through VISA and MASTERCARD that is presently spread all-inclusive. Although SET has numerous advantages over other proposals for straightforwardness and sociability, there seems to be an agreement on relative inefficiency of the protocol. In this paper, we simply give a brief overview of the secure electronic transaction with the help of the cryptography. This paper divide into different two sections in the first section give the brief introduction of the secure electronic transaction, the second section give the overview of the cryptography, third section for legal risk in electronic transaction and finally an overview of the secure transaction with the help of cryptography
