Proposal of New Block Cipher Algorithm


Speed and complexity are two important properties in the block cipher.The block length of the block cipher controls these two aspects. The speedlimitation enforces the designer to build block cipher system as hardwareprototype. In the same manner, the key complexity aspect acts as increasing theblock length, which will cause the increasing of complexity. In this paper, aproposed block cipher algorithm will be presented. Which includes non-linearfunction with new random key generators to generate all keys and a new approachfor S-box is used in this algorithm.
