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, 195-209 (2002).
Summary: We report on the design of Scream, a new software-efficient stream cipher, which was designed to be a “more secure SEAL”. Following SEAL, the design of Scream resembles in many ways a block-cipher design. The new cipher is roughly as fast as SEAL, but we believe that it offers a significantly higher security level. In the process of designing this cipher, we re-visit the SEAL design paradigm, exhibiting some tradeoffs and limitations.
