Cryptography is quite an old art where user can encrypt and decrypt the information using the strongest algorithm which is required for the specific task. But, the scope of this unique information hiding technology has been limited only to the field of software application. Data Encryption Standard (DES) is one of widely used standard for data encryption. Implementation of DES has been done in many ways. But in this proposed implementation, DES is implemented using Reversible logic. Till today not many inventions and growth is observed in reversible logic because of the high complexity in designing them.
