The Twofish Encryption Algorithm

A comprehensive description of the design goals for Twofish, together with the building blocks and general design of the cipher. The authors define the cipher in complete detail and present the performance of the algorithm on many platforms. They then go on to present their best cryptanalysis of Twofish and compare it with other ciphers, using various modes for Twofish including a family key variant. Complete details of the algorithm and its implementation are given in the appendix. Extremely useful to cryptographic researchers and practitioners responsible for implementing cryptography or security measures in their software.
