| Abstract | This paper is concerned with an extensive form of stream cipher Trivium. Trivium is extended to a scalable form by the coupling connection of Trivium-like shift registers. The characteristic polynomial of k Trivium-like shift registers in coupling connection is proved to have a factor of (1+x)k. So k-order primitive polynomials are defined in this paper. As the main contribution, a new stream cipher Quavium is proposed based on 4-round Trivium-like shift registers and k-order primitive polynomials. Quavium can also be used with 3 rounds. Experimental results show that Quavium is nearly as fast as Trivium and 3-round Quavium has a better performance. |
