F-Fcsr (Paperback)

High Quality Content by WIKIPEDIA articles! In cryptography, F-FCSR is a stream cipher developed by Thierry Berger, Francois Arnault, and Cedric Lauradoux. The core of the cipher is a Feedback with Carry Shift Register (FCSR) automaton, which is similar to a LFSR, but they perform operations with carries so their transition function is nonlinear. F-FCSR one of the eight algorithms selected for the eCRYPT networks eSTREAM Portfolio, but was later removed because after analysis showed weaknesses. Cryptography (or cryptology; from Greek, kryptos, "hidden, secret"; and, graph, "I write," or -, -logia, respectively) is the practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
