Daemen, Joan (ed.) et al., Fast software encryption. 9th international workshop, FSE 2002, Leuven, Belgium, February 4-6, 2002. Revised papers. Berlin: Springer (ISBN 3-540-44009-7). Lect. Notes Comput. Sci. 2365, 210-224 (2002).
Summary: Two ways of mounting distinguishing attacks on two similar stream ciphers, SOBER-t16 and SOBER-t32, are proposed. It results in distinguishing attacks faster than exhaustive key search on full SOBER-t16 and on SOBER-t32 without stuttering.
