	Security: Secure Internet Data Transmission. (Site not responding. Last check: 2007-10-08)
		Transmission security is the capability to send a message electronically from one computer system to another computer system so that only the intended recipient receives and reads the message and the message received is identical to the message sent.
		Security always involves a trade-off between the security of your data and the ease with which that data is accessible.
		The simplest measure of this security is the length of the keys used in your encryption algorithm.

	Roger Clarke's Crypto in Plain Text (Site not responding. Last check: 2007-10-08)
		An appropriate device to support secure storage of a private key is a chip, and the most practical carrier for such a chip at present is a smart-card.
		In this case, the private key never travels outside the owner's premises (or better still outside the owners' secure computer, or chip-card); but the owner must have the technical competence to perform the function, and all parties must have grounds to be confident about the quality of the key-generation process (e.g.
		It is important that the distinction be appreciated between secure deposit (for the benefit of the key-owner) and key escrow (for the benefit of a third party).

	Public Key Cryptography
		In asymmetric key cryptography, one key is used for encryption and another, mathematically related key, is used for decryption.
		Further, public key cryptography is used in situations where the recipient of a message must have confidence that the message received was received as intended by the sender and has not been altered or forged in any manner.
		Secure Sockets Layer (SSL) defined by Netscape is a popular application of public key cryptography found in Web-enabled applications requiring secure communications and authentication.

	HIPAA Security Rule
		The Security Rule is a key part of HIPAA -- federal legislation that was passed into law in August 1996.
		Security policies will also provide your organization with an overall security framework, ensuring that your security efforts are consistent and integrated rather than fragmented.
		Additionally, security policies are a clear mandate from senior management that security is a necessary and important part of your organization.

	RSA Security - 2.1.1 What is public-key cryptography?
		The generation, transmission and storage of keys is called key management (see Section 4.1); all cryptosystems must deal with key management issues.
		Because all keys in a secret-key cryptosystem must remain secret, secret-key cryptography often has difficulty providing secure key management, especially in open systems with a large number of users.
		For instance, some public-key cryptosystems are designed such that deriving the private key from the public key requires the attacker to factor a large number, it this case it is computationally infeasible to perform the derivation.

	SecurityDocs: Comment on Diffie-Hellman Key Exchange - A Non-Mathematician's Explanation (Site not responding. Last check: 2007-10-08)
		Asymmetric key systems alleviate that issue because they use two keys – one called the “private key” that the user keeps secret and one called the “public key” that can be shared with the world.
		Once secure exchange of the symmetric key is complete (and note that passing that key is the whole point of the Diffie-Hellman operation), data encryption and secure communication can occur.
		The longer a symmetric key is in use, the easier it is to perform a successful cryptanalytic attack against it.

	Security and Risk
		Based on an private key and an inverse public key, the public key is used by the sender to encrypt a message to the receiver, the receiver applies their private key to decrypt the message.
		Generally a key is generated as the composition of two large prime numbers which are needed for encryption and are difficult to determine given the key itself.
		Secure communication is then conducted using the shared secret key for encryption/decryption and a hash for message integrity.

	Computer security - Wikipedia, the free encyclopedia
		Such ultra strong secure operating systems are based on operating system kernel technology that can guarantee that certain security policies are absolutely enforced on an operating environment.
		Security is not an ancillary function of a computer application, but often what the application doesn’t do.
		Computer security is a highly complex field, and it is relatively immature, except on certain very secure systems that never make it into the news media because nothing ever goes wrong that can be publicized, and for which there is not much literature because the security details are proprietary.

		When many organizations think of secure transmission, the conversation generally turns to encryption and encrypted e-mail.
		The HIPAA Security Rule, references secure transmission and the use of encryption.
		One method of secure data transmission often used in conjunction with PKI to encrypt and authenticate large data files, is secure file transfer protocol (FTP).

	An IEEE 802.11 Wireless LAN Security White Paper
		DSSS operates by converting each bit of transmission into a "chip" sequence that is essentially a string of 1's and 0's that represent either the binary 1 or 0.
		Limited security is still maintained because the station will not be able to send or receive data correctly with an invalid WEP key (Paulo 2001, 12).
		The WEP algorithm is essentially the RC4 cryptographic algorithm from RSA Data Security, Inc. It is considered a symmetric algorithm because it uses the same key for enciphering and deciphering the plaintext Protocol Data Unit (PDU).

	Security
		Asymmetric key algorithms use a pair of keys that are created to work together — one key to encrypt a message and a second key to decrypt it.
		Recommended key lengths of 40, 75 and 128 bits are supported for incoming and outgoing EDI messages when used domestically; RC2 is limited by government restrictions to 40 bits when exported outside the US.
		Self-certification means that the exchange of public keys and certification of these keys must be handled as part of the process of establishing a trading relationship.

	Common Crypto Terms
		Key - Information (usually a sequence of random or pseudo-random binary digits) used initially to set up and periodically change the operations performed in crypto equipment for the purpose of encrypting or decrypting electronic signals, for determining electronic counter-countermeasures patterns (e.g., frequency hopping or spread spectrum), or for producing other key.
		Keying Variable - A setting or initial state of a key generator, such as a key card, key tape, mechanical permuter, or initial fill, which, when varied.
		A special key is used to encrypt the keys that are transmitted over the air and those are considered to now be "fl".

		The KOI-18 may be the oldest electrical key loader (the KY-38 used a mechanical key loader).
		There needs to be a way for the device that's holding the key to know that the key has been loaded without errors and maybe that it's the proper type of key for that device.
		The key being sent is encrypted with a Key Encryption Key (KEK) with equal to greater security than the key it's encrypting.
