Description: This paper discusses reconfigurable block encryption logic. Existing block cipher function designs have tended to deploy the secret bits in a specific and limited way. The authors generalize the role of the secret as truth tables of Boolean gates in a carefully designed logic schema. The authors' claims are: these reconfigurable functions are pseudo one-way and pseudo random functions. Such a function family is proposed using reconfigurable gates. Based on this function family the authors create REBEL, Reconfigurable Block Encryption Logic, which is an LR-Network. The authors prove cryptographic and cryptanalytic security for REBEL. From cryptographic perspective, this function is a pseudo-permutation. From cryptanalysis perspective, any observable attribute appears to be a random process.
