Data confidentiality grows equally important along with technological advancement. Encryption technique is an essential aspect of information security. The security of encryption technique relies on its key size used. Hence, a longer key in an encryption algorithm will be harder to break compared to an algorithm using a smaller key. This paper modified the RC6 Algorithm using a multidimensional key size to increase its security. A key size was selected using 1024, 1280, 1792, 2048, and 2816bits to vary the level of security of data that is being encrypted which caters an additional layer of security to brute force attack such as exhaustive search.
