Implementation of Pipelined Data Encryption Standard for Security Enhancement through Verilog

Abstract

This paper specifies a cryptographic algorithm in order to protect sensitive data. To maintain the data confidentially and to protect it, we need to convert the data into different form that differs completely from input and then transmit it. That data has to be again decrypted at the receiver. The algorithm defines the steps needed to encrypt the data and also to decrypt it. The pipelined DES has three modules: DES, pipeline, Control module. This design is programmed in Verilog. By pipelining we can achieve high throughput and by implementing triple DES, the security can be increased.
