چکیده
In the current rocket-speed growing E-commerce market, certain infrastructure, which enables users to exchange information and money securely over the Internet, is essential. Unfortunately, Internet is mere a cloud of connections of nodes. There is no organization to operate and manage. So the Internet itself is not responsible for any malicious frauds and attacks, and failures caused by reliability problems. Public Key Infrastructure (PKI) has been the solution to insecure communication over the network including above E-commerce problem. PKI is indispensable in the present Internet environment. This paper summaries papers about secure communication over network using PKI as well as reviews the infrastructure and the role of Public Key in current Internet.
