K. John Singh, R. Manimegalai · 2015
Rapid advancements in information technology world resulted in the drastic growth in the amount of data transferred through the network. Networks used for multimedia communication do not provide much security for data transfer as well as digital communication. Billions of people use internet options for essential communication and as a tool for commercial interests. Therefore, security is an enormously important issue to deal with. As web services also have data storage and data communication, we need to protect and provide confidentiality. There is a need to recognize the different aspects of security and their applications. This paper provides a comprehensive overview of evolution of encryption algorithms right from ancient cryptography techniques to modern encryption algorithms.
