Abstract

 

 

The data encryption standard was the first encryption system to meet the National Institute of Standards and Technology’s requirements for an encryption system, and also the first standardized encryption system. It was standardized in 1977 and since then, it has been subject to criticisms. The successor to the Data Encryption Standard, Advanced Encryption Standard has been developed and is used today but the Data Encryption Standard is still used today in industries. This paper overviewed the Data Encryption Standard; criticisms faced and concluded if it is still secure enough to protect our confidential information based on published cryptanalysis on this encryption system.

Key words: Block ciphers, TDEA, DES, AES, cryptanalysis, encryption, decryption, cryptography.
