	Quantum cryptography - Wikipedia, the free encyclopedia
		Unlike traditional cryptography, which employs various mathematical techniques to restrict eavesdroppers from learning the contents of encrypted messages, quantum cryptography is based on the physics of information.
		Whereas classical public-key cryptography relies on the computational difficulty of certain hard mathematical problems (such as integer factorisation) for key distribution, quantum cryptography relies on the laws of quantum mechanics.
		Quantum cryptography is still vulnerable to a type of MITM where the interceptor (Eve) establishes herself as "Alice" to Bob, and as "Bob" to Alice.

	Quantum Cryptography Tutorial
		Cryptography is the art of devising codes and ciphers, and cryptoanalysis is the art of breaking them.
		They produced "BB84," the first quantum cryptography protocol, in 1984, but it was not until 1991 that the first experimental prototype based on this protocol was made operable (over a distance of 32 centimeters).
		This protocol is complicated by the presence of noise, which may occur randomly or may be introduced by eavesdropping.

	Perfect forward secrecy - Wikipedia, the free encyclopedia
		In an authenticated key agreement protocol that uses public key cryptography, perfect forward secrecy (or PFS) is the property that disclosure of the long-term secret keying material that is used to derive an agreed ephemeral key does not compromise the secrecy of agreed keys from earlier runs.
		PFS requires the use of public key cryptography, and cannot be achieved with symmetric cryptography alone.
		Off-the-Record Messaging, a cryptography protocol and library for many instant messaging clients, providing perfect forward secrecy as well as deniable encryption.

	Kerberos protocol - Wikipedia, the free encyclopedia
		Kerberos is a computer network authentication protocol which allows individuals communicating over an insecure network to prove their identity to one another in a secure manner.
		The protocol was named after the Greek mythological character Kerberos (or Cerberus), known in Greek Mythology as being the monstrous three-headed guard dog of Hades.
		Some Microsoft additions to the Kerberos suite of protocols are documented in RFC 3244 "Microsoft Windows 2000 Kerberos Change Password and Set Password Protocols".

	RSA Security - 3.6.1 What is Diffie-Hellman?
		The Diffie-Hellman key agreement protocol (also called exponential key agreement) was developed by Diffie and Hellman [DH76] in 1976 and published in the ground-breaking paper "New Directions in Cryptography." The protocol allows two users to exchange a secret key over an insecure medium without any prior secrets.
		The authenticated Diffie-Hellman key agreement protocol, or Station-to-Station (STS) protocol, was developed by Diffie, van Oorschot, and Wiener in 1992 [DVW92] to defeat the man-in-the-middle attack on the Diffie-Hellman key agreement protocol.
		In recent years, the original Diffie-Hellman protocol has been understood to be an example of a much more general cryptographic technique, the common element being the derivation of a shared secret value (that is, key) from one party's public key and another party's private key.

	Single photons distributed for quantum cryptography
		The quantum cryptography is expected to be the last resort of the cryptography protocol, and to enhance enormously the safety of transmitting information.
		The result was enabled by combining the original protocol of the quantum cryptography developed by the collaboration of NTT and Stanford University (USA) and the NTT developed optical switch to control the flow of photons.
		Quantum cryptography is seen as the next generation cryptographic system to replace the public-key protocol for protecting data.

		The NRL Protocol Analyzer is a prototype special-purpose verification tool, written in Prolog, that has been developed for the analysis of cryptographic protocols that are used to authenticate principals and services and distribute keys in a network.
		Initially in any protocol, there are at least two types of trust: trust that designated participants, or groups of participants, will faithfully execute their assigned function in the protocol and trust in the integrity of the transfer mechanism(s) integral to the protocol.
		In this paper we present a protocol to show that both BAN and AT are not expressive enough to capture all of the kinds of flaws that appear to be within their scope.

	An Overview of Cryptography (Site not responding. Last check: 2007-10-30)
		Cryptography is the science of writing in secret code and is an ancient art; the first documented use of cryptography in writing dates back to circa 1900 B.C. when an Egyptian scribe used non-standard hieroglyphs in an inscription.
		With this form of cryptography, it is obvious that the key must be known to both the sender and the receiver; that, in fact, is the secret.
		The OAKLEY Key Determination Protocol, described in RFC 2412, is a key determination and distribution protocol using a variation of Diffie-Hellman.

	Financial Cryptography: The protocol wars
		I didn't have much to say, because by the time they got to me, the protocols were either pretty "correct" or too big to absorb.
		I'd noticed that the stack of protocols was exploding - upwards, sideways, backways, every way you could think of - but there wasn't that much evidence that anyone except big corporates was doing any implementation.
		However it was rejected for 1) it went directly to the LAN/MAC interface (forbidden because LAN/MAC doesn't exist in the OSI model) and 2) it wen directly from layer 4 to MAC layer (bypassing the layer 3/4 interface, also a violation of the OSI model).

	E-mail - Wikipedia, the free encyclopedia
		A number of protocols were developed to deliver e-mail among groups of time-sharing computers over alternative transmission systems, such as UUCP and IBM's VNET e-mail system.
		Roughly at the same time, the IETF developed a much simpler protocol called the Simple Mail Transfer Protocol (SMTP) which has become the de facto standard for e-mail transfer on the Internet.
		Users download their messages from servers usually with either the POP or IMAP protocols, though in a large corporate environment users are likely to use some proprietary protocol such as Lotus Notes or Microsoft Exchange Servers.

	what is cryptography - Q&A
		Cryptography is protocol(set of rules) to send and recieve secure data delivery from source to exact destination.
		cryptography consists of an algorithm by which encryption and decryption of data is possible so that authenticate and secure data can be exchanged between the receiver and the sender.
		Cryptography is a science of keeping secrets secret, that is, it is a method of sending messages in disguised form.

	Print the story
		Nippon Telegraph and Telephone Corp. has successfully demonstrated the quantum cryptography with a single photon, whose state is so fragile against the attacks from the eavesdroppers, can be realized in the photonic network of optical fibers.
		Quantum cryptography is assumed as a next generation cryptographic system that may replace the public-key protocol.
		Although the quantum cryptography breaks the vicious circle mentioned above, it is required that the very weak signal of single photon and strong light signal currently used in photonic network can transmit in the same network.

		Again, depending on the protocol being tunneled, it may be possible for Mallet to use the write channel he controls to get data sent on the read channel he controls.
		The tinc handshake protocol would also make a nice homework exercise for students in computer security courses, since it's not trivially broken but does exhibits various textbook handshake-protocol flaws, violating a great many of the general principles of secure protocol design: - Don't use the same key for encryption and authentication.
		Authors contacted, their response was that the problems were not that serious, and that a main goal of tinc was to get the opportunity to experiment with secure tunneling protocols and mechanisms (other design goals are at http://tinc.nl.linux.org/goals)).
