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 properties. Simulation with ENT randomness test program confirms randomness of output keystream with very good results.
