New Guess-and-Determine Attack on the Self-Shrinking Generator
We propose a new type of guess-and-determine attack on the self-shrinking generator (SSG). The inherent flexibility of the new attack enables us to deal with different attack condi...

Doubly-Focused Enumeration of Pseudosquares and Pseudocubes
This paper offers numerical evidence for a conjecture that primality proving may be done in (log N)3+o(1) operations by examining the growth rate of quantities known as pseudosquar...

New Attacks Against Reduced-Round Versions of IDEA
In this paper, we describe a sequence of simple, yet efficient chosen-plaintext (or chosen-ciphertext) attacks against reduced-round versions of IDEA (with 2, 2.5, 3, 3.5, and 4 ro...
