Puneet Kumar Kaushal, Rajeev Sobti, Dr. G. Geetha . Random Key Chaining (RKC): AES Mode of Operation. International Journal of Applied Information Systems. 1, 5 ( February 2012), 39-45. DOI=10.5120/ijais12-450184
There is a compelling need for a mode of operation that can efficiently provide authenticated encryption at a higher data rate, and is capable of making use of pipelining and parallel processing. This paper describes Random Key Chaining (RKC) block cipher mode of operation that fills this need. RKC mode makes use of Deterministic Random Bit Generator (DRBG) andwith the application of DRBG every block of plaintext is being encrypted with a different key bringing it closer to one-time pad approach. The slight variation of RKC mode can be used as a confidentiality mode that can be used in application like hard-disk compression with reduced computational cost.
