Src : Hybrid block cipher method

الملخص EN

The principal goal guiding the design of any encryption algorithm must be the security.

In the real world, however, performance and implementation cost are always of concern.

Making the assumption that the major AES candidales are secure the most important properties the algorithms will he judged on will be the performance and cost ofimplementation.

In this paper, a new secret-key block cipher called SRC, is proposed.

The block size is 128 bits؛ and the key can be any length up to 256 b^es.

The proposed algorithm is designed to take advantage of the powerful, which is supported by RC6 and Serpent algorithms with overcoming their weaknesses, resulting in a much improved security/performance tradeoff over existing ciphers.

As a result, this proposed algorithm offers better security than RC6 and Serpent algorithms.

And it is compact, speed, simplicity and easy to understand.

It adapts key dependent permutation and combines different algebraic group which is adapted from RC6 algorithm.

So that the SRC algorithm will be combined the Serpent and RC6 algorithms to obtain security / performance tradeoff and fastest algorithm.
