MICKEY

From Wikipedia, the free encyclopedia

In cryptography, Mutual Irregular Clocking KEYstream generator (MICKEY) is a stream cipher algorithm developed by Steve Babbage and Matthew Dodd.^[1] The cipher is designed to be used in hardware platforms with limited resources, and was one of the three ciphers accepted into Profile 2 of the eSTREAM portfolio. The algorithm is not patented and is free for any use.^[2]

Structure

The cipher maps an 80-bit key and a variable length initialization vector (0 to 80 bits) to a keystream with a maximum length of 2⁴⁰ bits.

Cryptanalysis

As of 2013, a differential fault attack has been reported against MICKEY 2.0 by Subhadeep Banik and Subhamoy Maitra..^[3]
