3D: A Three-Dimensional Block Cipher
Abstract. The main contribution of this paper is a new iterated secretkey block cipher called 3D, inspired by the AES cipher. The 3D cipher has an SPN design, operates on 512-bit blocks, uses 512-bit keys, iterates 22 rounds, and employs a 3-dimensional state, instead of the 2dimensional matrix of the AES. The main innovation of 3D includes the multi-dimensional state, generalizing the design of Rijndael, and allowing block sizes beyond the 256-bit boundary. This features motivates the use of 3D as a building block for compression functions in hash functions, MAC and stream cipher constructions requiring large internal states. We explain the design decisions and discuss the security of 3D under several attack settings.
