Algebraic Attacks on SOBER-t32 and SOBER-t16 without Stuttering
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
This paper presents algebraic attacks on SOBER-t32 and SOBER-t16 without stuttering. For unstuttered SOBER-t32, two different attacks are implemented. ...
The complexity of attack is around O(2 100 ) with 2 92 keystream observations. The second algebraic attack is applicable to SOBER-t16 without stuttering. ...
Acknowledgment We are grateful to Greg Rose, Frederik Armknecht and unknown referees for their very helpful comments. ...

In this paper we show that the algebraic attack method previously applied to SOBER-t32 is prevented from succeeding on SSS by the use of the keydependent substitution box (SBox) in the nonlinear filter ...
Both the SSS and SOBER-t32 stream cipher designs use a single word-based shift register and a nonlinear filter function to produce keystream. ...
As the algebraic attack on SOBER-t32 without stuttering [3] was successful, and the two ciphers have similar designs (and SSS does not employ stuttering), we have attempted to modify the SOBER-t32 attack ...
