Rivest Cipher 5 (RC5)
The RC5 algorithm was derived from the RC4 algorithm. While you read take note of the year RC5 was published. How much time was there between the development of RC4 and RC5? What type of symmetric cipher is RC5? Compare the three components of RC5 with the components of AES, do you see any similarities?
Cryptography is the art or science encompassing the principles and methods of transforming an intelligible message into one that is unintelligible and then retransforming that message back to its original form . The security in computer systems can be increased by is encrypting and decrypting the data. In this technique original message is called plain text. Encryption is the process of converting the plain text (original message) into cipher text (encrypted text). Decryption is the process of transferring the cipher text (encrypted text) into Plain Text (original message) which is shown in figure 1. Encryption and decryption are controlled by cryptographic keys.
