A cryptographic system is to be implemented in an information processing system. Many of IT applications will be realized as embedded systems, which reiy on security mechanisms.There is a particulariy simple relationship between the operations of decipherment and encipherment. One of the application of cryptographic methods to protect information-processing system is Data Encryption Standard (DES).If cryptography is to be used to protect communications between a terminal and host processor;the key is very important.DES has a 56-bits keys. The security of an algorithm rests in the key; using a cryptographically weak process to generate keys, the whole system is weak. Some encryption algorithms have weak-keys, specify keys that are less secure than the other keys. This system analyze weak-keys on Data Encryttion Standard such as weak-keys, semi-weak keys and possible weak-keys depend on DES algorithm.
