Solving Semantic Problems in ‘Chaff and Winnowing’ Problem by Using Cryptography

Abstract

The need to secure the Internet is clear to everyone consequently more and more mechanisms to provide security and enhance it at different layers and different applications are being developed. Thus we want to introduce a new and secure method in network security. In this article at first we will survey ”chaff and winnowing” method and cryptography method. Then we will discuss about their advantages and disadvantages and we will introduce a new method which it can solve the ”chaff and winnowing” method’s semantic challenges and make cryptography method safer. This new method uses the advantages of both methods and tries to omit the disadvantages of before methods to make a secure method for general using. Also this method is efficiency in confidentially and authentication problems.
