Analysis of Encryption Techniques for Secure Communication

The process of digitization observed among various industries has led to significant amount of collection, processing, sharing and alteration of data. The rapid continuous increase in exchange of data over networks and cloud has encouraged activities such as unauthorized access, illegal usage, alteration of transmitted and stored data. Data security issues are now becoming important as society is moving towards digital age. To get over this problem encryption techniques plays vital role. Modern encryption techniques provides solution to these problems. This paper provides an overview of encryption techniques through which data security can be enhanced. In this paper analysis of security features and steps involved in designing of most broadly used symmetric encryption algorithms like DES, 3DES, AES is done. Furthermore analysis and comparison of these encryption process according to entropy, floating frequency and histogram is done.
