Distinguishing Attack on Bivium
Bivium is a simplified version of Trivium, a hardware profile finalist of eSTREAM project. Bivium has an internal state of size 177 bits and a key length of 80 bits. In this paper we introduce a distinguishing attack on this cipher. In this method we first find the best linear approximation for the updating function.

Bivium is a reduced version of the stream cipher Trivium, using 177 stages and only 2 feedback registers. In this paper, we present a cube tester which combines the cube attack with efficient algebraic property-testers. By this method, Bivium was broken with complexity about 2^26 simulations.

Attacking Bivium and Trivium with the Characteristic Set Method
In this paper we utilize an algebraic method called the characteristic set method to attack Bivium and Trivium in the guess-and-determine way. Our attack focuses on recovering the internal states of these two ciphers. We theoretically analyze the performance of different guessing strategies in the guess-and-determine method and present a good one.

RFID Authentication Protocol with Enhanced-Bivium
RFID (radio frequency identification) is a small electronic device that consists of small chip and an antenna. The biggest challenge for RFID technology is to provide benefits without degrading the secutiry level. This paper proposes a new RFID authentication protocol based on the lightweight stream cipher Enhanced-Bivium.

Cube attack on reduced-round Enhanced-Bivium
Trivium is a notable light-weight synchronous stream cipher submitted to the European eSTREAM project in April 2005. Enhanced-Bivium is a reduced version of Trivium which is suitable for RFID system. In this paper, the security of Enhanced-Bivium is concerned under cube attack, which is one of the best known attack on the reduced round Trivium proposed
