A new SNOW stream cipher called SNOW-V

SNOW - a new stream cipher?

In this paper a new word-oriented stream cipher, called SNOW, is proposed. The design of the cipher is quite simple, consisting of a linear feedback shift register, feeding a nite state machine. The design goals of producing a stream cipher signi cantly faster than AES, with signi cantly lower implementation costs in hardware, and a security level similar to AES is currently met. Our fastest C ...

A New Version of the Stream Cipher SNOW

In 2000, the stream cipher SNOW was proposed. A few attacks followed, indicating certain weaknesses in the design. In this paper we propose a new version of SNOW, called SNOW 2.0. The new version of the cipher does not only appear to be more secure, but its implementation is also a bit faster in software.

The New Heuristic Guess and Determine Attack on Snow 2.0 Stream Cipher

SNOW 2.0 is a word oriented stream cipher that has been selected as a standard stream cipher on ISO/IEC 18033-4. One of the general attacks on the stream ciphers is Guess and Determine attack. Heuristic GD attack is GD attack that represents an algorithmic method to analysis the stream cipher with the variables of the same size. The results of HGD attack on TIPSY, SNOW 1.0 and SNOW 2.0 stream c...

A New Stream Cipher: Dicing

In this paper, we will propose a new synchronous stream cipher named DICING, which can be viewed as a clock-controlled one but with a new mechanism of altering steps. With the simple construction, DICING has satisfactory performance, faster than AES about two times. For the security, there have not been found weakness for the known attacks, the key sizes can be 128bits and 256bits respectively. .
