Enhanced block ciphers with data-dependent rotations
TL;DR: A plaintext message to be encrypted is segmented into a number of words, and an integer multiplication function is applied to a subset of the words, e.g., to the two words in registers B and D as mentioned in this paper.

Secure user identification based on constrained polynomials
Jeffrey Hoffstein,Burton S. Kaliski,Daniel Lieman,Matthew John Barton Robshaw,Yiqun Lisa Yin +4 more
TL;DR: In this article, the authors proposed a scheme for providing secure user identification or digital signatures based on evaluation of constrained polynomials. But their scheme requires the verifier to verify the identity of the prover by evaluating a function of information contained in at least a subset of the commitment signal, the challenge signal, and the response signal.

On the Design and Security of RC2
TL;DR: The block cipher RC2 was designed in 1989 by Ron Rivest for RSA Data Security Inc. as mentioned in this paper, and preliminary attempts to use both differential and linear cryptanalysis have been made.
Book ChapterDOI
Improved Analysis of Some Simplified Variants of RC6
TL;DR: Simplified variants that omit a quadratic function and a fixed rotation in RC6 are examined to clarify their essential contribution to the overall security of RC6.
RC6 as the AES.
TL;DR: Each of the finalist algorithms appears to offer adequate security, and each offers a considerable number of advantages, but each has one or more areas where it does not fare quite as well as some other algorithm.
