Information security is becoming much more important in data storage and transmission with the fast progression of digital data exchange in electronic way. Cryptography has come up as a solution which plays a vital role in information security system against malicious attacks. The cryptography is most important aspect of communications security and becoming an important building block for computer security. This security mechanism uses some algorithms to scramble data into unreadable text which can be only being decoded or decrypted by party those possesses the associated key. To protect sent messages that some of the most commonly used cryptography methods with private key based algorithm are LOKI 89, 91, 97 , DES, triple DES, AES, Blowfish, etc. These algorithms also include several computational issues as well as the analysis of DES algorithm. The main features that specify and differentiate one algorithm from another are the ability to the speed of encryption and decryption of the input plain text. This paper analyzes the private key based algorithm DES and LOKI91 by computing index of coincidence IC and time efficiency.
