In cryptography, the use of the symmetric key encryption is common to ensure data integrity. Symmetric key encryption code can be divided into the block cipher and stream one. RC6 is a symmetric key block cipher derived from RC5. It was designed by Ron Rivest, Matt Robshaw, Ray Sidney and Yiqun Lisa Yin to meet the requirements of the Advanced Encryption Standard (AES) competition. The algorithm was one of the five finalists and was also submitted to the NESSIE and CRYPTREC projects. It is a proprietary algorithm, patented by RSA Security.
