Design of secure light-weight stream ciphers is an important area in cryptographic hardware & embedded systems and a very recent design by Armknecht and Mikhalev (FSE 2015) has received serious attention that uses shorter internal state and still claims to resist the time-memory-data-tradeoff (TMDTO) attacks. An instantiation of this design paradigm is the stream cipher named Sprout with 80-bit secret key. In this paper we cryptanalyze the cipher and refute various claims. The designers claim… CONTINUE READING
