	Mod n cryptanalysis - Wikipedia, the free encyclopedia
		In cryptography, mod n cryptanalysis is an attack applicable to block and stream ciphers.
		The method was first suggested in 1999 by John Kelsey, Bruce Schneier and David Wagner and applied to RC5P (a variant of RC5) and M6 (a family of block ciphers used in the FireWire standard).

		Cryptanalysis (from the Greek kryptós and analýein, "to loosen" or "to untie") is the study of methods for obtaining the meaning of encrypted information without access to the secret information which is normally required to do so.
		However, cryptanalysis usually excludes attacks that do not primarily target weaknesses in the actual cryptography; methods such as bribery, physical coercion, burglary, keylogging, and so forth, although these latter types of attack are an important concern in computer security, and are increasingly becoming more effective than traditional cryptanalysis.
		Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography — new ciphers being designed to replace old broken designs, and new cryptanalytic techniques invented to crack the improved schemes.

		Cryptanalysis (from the Greek kryptÃ³s, "hidden", and analÃ½ein, "to loosen" or "to untie") is the study of methods for obtaining the meaning of encrypted information, without access to the secret information which is normally required to do so.
		Cryptanalysis has coevolved together with cryptography, and the contest can be traced through the history of cryptography â€” new ciphers being designed to replace old broken designs, and new cryptanalytic techniques invented to crack the improved schemes.
		Although the actual word "cryptanalysis" is relatively recent (it was coined by William Friedman in 1920), methods for breaking codes and ciphers are much older.

	Cryptology
		The public key is therefore the pair n and e, the private key is the pair n and d.
		The cryptanalysis of single-key cryptosystems depends on one simple fact - that some traces of the original structure of the plaintext may be visible in the ciphertext.
		Cryptanalysis of public key ciphers is therefore virtually indistinguishable from research into any other area of mathematics.

		We also show mod 5 and mod 257 attacks against M6, a cipher proposed in the FireWire standard.
		We expect mod n cryptanalysis to be applicable to many other ciphers, and that the general attack is extensible to other values of n.

		Kahn goes on to mention increased opportunities for interception, bugging, side channel attacks and quantum computers as replacements for the traditional means of cryptanalysis [1] (http://www.fas.org/irp/eprint/kahn.html).
		Successful cryptanalysis has undoubtably influenced history; the ability to read the presumed-secret thoughts and plans of others can be a decisive advantage, and never more so than during wartime.
		Numbers with several hundred digits are still considered too hard to factor in 2004, though methods will probably continue to improve over time, requiring key size to keep pace or new algorithms to be used.
