The SHADE cipher: an efficient hash-function-based Feistel network

We propose SHADE, a balanced Feistel network (H. Feistel, 1973; H. Feistel et al., 1975) that uses a modified hash function that accepts two fixed size inputs (each of which is the size of the function output) as the round function. This new hash function blends many of the concepts of MD5 and SHA-1, with some modifications and extensions. A complete description of the SHADE cipher, including key schedule, blocksize, round (hash) function, and number of rounds, is presented
