Description
This paper describes the design principles, the specification, and evaluations of a new 128-bit block cipher E2, which was proposed to the AES(Advanced Encryption Standard)candidates.This algorithm supports 128-bit, 192-bit, and 256-bit secret keys.The design philosophy of E2 is highly conservative;the structure uses 12-round Feistel as its main function whose round function is constructed with 2-round SPN structure, and initial / final transformational functions.E2 has practical security against differential attack, linear attack, cryptanalysis with impossible differential, truncated differential attack, and so on.Furthermore, E2 can be implemented efficiently and flexibly on various platforms because the primitive operations involve byte length processing.
