In this modern age information sharing and transfer has increased exponentially. The information shared is vulnerable to unauthorized access and inception. Cryptography is used to provide secrecy in message transmission. The Simplified Data Encryption Standard or in short S-DES algorithm is used to encrypt messages to form secret text. The previously used SDES technique can be strengthed by use of randomized key generation techniques which will strengthen the secrecy of the message to be transferred.
