Title
Erc5a-An Enhanced Rc5 Algorithm On Bit Propagation In The Encryption Function
Abstract
In this paper presents an enhancement to the encryption function of RC5 algorithm which addresses the poor hit propagation or avalanche effect in the early rounds of the algorithm. This weakness has made RCS to use excessive rounds in its encryption function. The enhanced RC5 algorithm (ERC5a) improves bit propagation as early as first round without using expensive operations in the design of RC6. Comparative security evaluation has been conducted for the proposed ERC5a and classic RC5. Simulation in C language both for RC5-32/12/16 and ERC5a-32112/16 was performed by applying 36 million random plaintexts (64-hit) for each round resulted in a 74.41% increase in hamming distance in the first round, 35.48% in the second round, and 9.67% in the third round which means that the proposed ERC5a algorithm has a better hit propagation in its encryption function. Thus, the resulting enhancement can reduce the number of rounds, reduce memory requirement and achieve better performance for all existing RCS implementations especially for lightweight devices where these properties are deemed significant.
