The Study And Application Of E-Commerce Security Scheme Based On Cryptology

As the application of global E-commerce is closing in upon, the security of E-commerce has become the focus everybody cares. The paper studies security problem of E-commerce by utilizing cryptology,and discusses the integrated method of secure E-commerce application to fulfill its confidentiality, integrality, authentication, and non-repudiation.Firstly, the paper summarizes the E-commerce security and cryptology actuality. By synthesizing encryption algorithms, the paper improves on digital signature method based on cryptology. This scheme integrates several encryption algorithms. Secondly, Contraposing that digital signature schemes presently mainly validate sender and invader, the paper designs a digital signature method to validate the receiver. The method settles the security question lies in E-commerce presently. Finally, the paper gives an application example to demonstrate the procedure of digital signature .The example can fulfill the idea put forward in the paper.Keywords:Secure E-Commerce,Encryption,Decryption,Digital Signature,Hash Function,Message Digest...
