This paper specifies Alamout, a new hardware oriented synchronous stream cipher with an associated authentication mechanism. The design is small in hardware and it targets environments with limited resources. Alamout supports key size of 80 bits and IV size of 128 bits. The Alamout cipher has been designed to produce keystream with guaranteed randomness(More)
This paper presents a compact implementation of the S-Box of Pomaranch stream cipher using composite field arithmetic in GF((2<sup>3</sup>)<sup>3</sup>). It describes a systematic exploration of different choices for the irreducible polynomials that generate the extension fields. It also examines all possible transformation matrices that map one field(More)
