A Survey Paper on Cryptography Techniques

In the modern era evaluation of networking and wireless networks has come in information and communication technology, there are so many things that gives facility to deal with these technology using internet. In internet email security is main aspect and the process of cryptography plays an important role to provide the security to the networks. To improve security and efficiency, most email system adopt Public Key Infrastructure (PKI) as the mechanism to implement security, but public key infrastructure based systems suffer from expensive certificate management and problems in scalability. The main objective of this approach is awareness of email security and its requirements to the common computer users. A number of cryptographic techniques are developed for achieving secure communication. The proposed mailing system is secure against standard security model.
