【Abstract】 With the rapid development and popularization of internet, E-Commerce is widely used in our daily life. More and more people pay attention to the security problems of E-Commerce: confidentiality, integrity, availability, controllability, non-repudiation and accountability. In cryptology, those problems are solved by public key technology. Public key infrastructure (PKI) is the base and core of network security, it can provide good security services for the world of network, by using asymmetric encryption algorithms. This paper takes E-contract as an example and puts forward the solution of E-Commerce by using technology PKI.更多还原
