COZMO - A New Lightweight Stream Cipher

This paper manages the merger of the two lightweight stream figures – A5/1 and Trivium. The thought is to make the key stream more secure and to remove the vulnerabilities of the individual ciphers. The bits created by the Trivium figure (yield) will go about as the contribution of the A5/1 figure. The registers utilized as a part of the A5/1 figure will be filled by the yield bits of the Trivium figure. The three registers will then be associated to produce a yield which will be our required key stream.
