The Study On The Secure Scheme Of Electronic Transaction Based On SET

Electronic transaction is the key of E-commerce. The security of electronic transaction is the main cause that slows its development. In this paper, cryptology and the secure technology in E-commerce were discussed firstly. Then a secure solution for B2B electronic transaction was presented, according to SET.This solution not only has the security of SET, but also fits for the mode of B2B transaction more suitably. It can prevent the transaction from the dupery that comes from the buyer or the seller. The count-based payment mode facilitates the transaction between companies. In this solution, the entity in transaction also can sign for the transaction data more flexibly, more securely and more reasonably, with the use of multi-signature.At last, to test the solution presented in this paper before, a simulative B2B website for selling household appliances was designed. The website not only manifests the difference between SET and the solution, but also verifies the security and the feasibility of the solution. So the secure solution of B2B electronic transaction has some practical value. At the beginning of B2B E-commerce in our country, it can be used for reference.
