		Bulk Encryption - 3DES and AES Encryption - Layer 2 Encryption Datacryptor
		With triple DES (168-bit) or AES (128, 192, 256-bit) algorithms built in, or using other customized, or national algorithms, it is the first family of encryption products to offer algorithm flexibility and protocol agility.
		This means that not only can the unit be programmed with different cryptographic algorithms as specified by the customer, but depending on the infrastructure and certain physical limitations, the same unit can be loaded to support various communications protocols.

	A Bulk Data Encryption Algorithm
		We attempt to design an encryption system for medium speed encryption of blocks, and of high security.
		It is intended to be fast on most modern computers, and relies on repeated table use and having a large state space.
		We have given a simple fast encyphering algorithm, suitable for large bulk data, and for short messages where one key is changed.

		Because symmetric key encryption is commonly used to conduct bulk encryption of data, it is sometimes referred to as bulk encryption.
		Encryption algorithms are referred to as ciphers, and the technique used by the cipher to accomplish encryption is usually included as part of its more descriptive name.
		For example, a symmetric cipher that applies encryption one block at a time, where a block is defined as a certain number of bits transformed by the cipher as a single unit, is known as a symmetric block cipher.

		(Data Encryption Standard) is the symmetric encryption algorithm defined and endorsed by the U.S. Government in 1977 as an official standard.
		DES operates on 64 bit blocks with a 56-bit key and works well for bulk encryption.

	Dr. Dobb's \| Programming Public Key CryptoStreams, Part 1 \| January 23, 2004
		That is, when the encryption employed uses a symmetric encryption algorithm, where the same key is used for both encryption and decryption, the computer that applies the encryption must never become compromised or else its encryption keys and all data security are also compromised.
		Encryption applied using a symmetric algorithm in an untrustworthy environment is either untrustworthy or pointless.
		Symmetric encryption is useful to protect data on demand, where only an authorized user with a copy of the encryption key can decipher and use the data and the key is never stored on the computer for it to use later in automatic decryption.

		This is the lowest level of encryption, and because the value of one chunk is small, it is where we use the fastest and weakest level encryption.
		Hierarchical encryption generalises and improves on the two-level PGP encryption process, as it intentionally tailors the strength of the encryption at any level to the value and lifespan of the data being encrypted.
		Hierarchical encryption and fragmentation with signal diversity are all the better when combined with technologies for ensuring that data, whether legitimately received or not, are not subsequently misused.

	Using field encryption in applications
		Encryption, in layman's terms, is the application of transformations to data in order to hide information while it is stored or communicated.
		RSA Security is a company that pioneered the commercialization of so-called "public key" encryption techniques based on complex mathematical transformations, and Lotus Notes was the first major commercial application to adopt their technology.
		Asymmetric encryption is commonly known as public key encryption, because the actual encryption is always done using a key that doesn't have to be kept secret.

	XML Encryption Programming
		Encryption is fairly simple if you are trying to encrypt a DOM structure.
		It uses a randomly generated key to handle the bulk encryption, and then encrypts this using an RSA public key.
		A private key is loaded as a Key Encryption Key (KEK), and a call is made to the library which decrypts the encrypted data and inserts the resulting DOM nodes back into the original document.

	A Very Basic Introduction to Data Encryption (Site not responding. Last check: )
		Encryption is the procedure of transforming plaintext, data that can be read by anyone, to ciphertext, data that can only be read by someone with a secret decryption key.
		Public Key encryption was invented in 1976 to overcome the problems associated with secret key encryption: managing the secret key.
		Encryption software may only be exported from the United States with a license from the State Department.

	CIOL : Security : SSL protocol: Tackling performance issues (Site not responding. Last check: )
		There are two aspects to the encryption; the initial asymmetric key generation that establishes the authenticity of the communicating parties; and the bulk encryption of the information served.
		Bulk encryption is not as computationally taxing on the server as the initial process of authentication (or handshake).
		This is because after the handshake the key for bulk encryption has to be generated once.

	When Good Security Leads to Poor Performance
		But once the SSL encryption is enabled, that 5-second wait jumps to almost 40 seconds.
		Although the devices are different, the concept is basically the same: off-load the SSL encryption to another device to free valuable Web server CPU cycles for other duties.
		One system requires a card to be installed and maintained in each server; the other consists of a piece of equipment that could become a single point of failure if you don't have a second unit as a hot standby.

		DES [16], the workhorse encryption algorithm for the past fifteen years, is nearing the end of its useful life.
		If the world is to have a secure, unpatented, and freely- available encryption algorithm by the turn of the century, we need to develop several candidate encryption algorithms now.
		A standard encryption algorithm must be implementable on a variety of different platforms, each with their own requirements.

	Oracle HTTPS for Client Connections
		But the weakness of symmetric encryption is that the same key has to be known by both parties, and if anyone intercepts the exchange of the key, then the communication becomes insecure.
		The client encrypts the bulk key with the server's public key, and sends the encrypted bulk key to the server.
		The bulk encryption key is securely exchanged using the PKI public key, and is then used for the encryption of further communications on the channel.

	» Is encryption really crackable? \| George Ou \| ZDNet.com
		When I sent out this alert about Banks not using SSL to prove their identity to their users, quite a bit of feedback was excessively cynical on encryption technology and cryptography in general along the lines of "it’s useless anyways".
		Further propelling the myth that encryption is worthless is that I often hear people saying that they heard that a 512 bit RSA key was broken.
		Encryption strength and the number of bits used are selected based on how many decades the data needs to be kept safe.

		Encryption is the most effective way to achieve data security.
		A bulk encryption process will start the first time you log-in after Credant Windows Shield is installed.
		This is a significant, because if encryption is used to protect personal information that is stored, accessed or even displayed on a mobile device, then there is no notification requirement if the device is lost, stolen or attacked, as the information is protected by the encryption.

	TRANSPARENT ENCRYPTION AND SEPARATION OF DUTIES FOR ENTERPRISE DATABASES
		The sooner the encryption of data occurs, the more secure the environment—however, due to distributed business logic in application and database environments, it is not always practical to encrypt data as soon as it enters the network.
		Encryption performed by the DBMS can protect data at rest, but you must decide if you also require protection for data while it’s moving between the applications and the database.
		One of the essential components of encryption that is often overlooked is key management, which refers to the way cryptographic keys are generated and managed throughout their life.

	Linux.com - Cryptographic Algorithms and Protocols
		So-called ``exportable'' encryption algorithms only have effective key lengths of 40 bits, and are essentially worthless; in 1996 an attacker could spend $10,000 to break such keys in twelve minutes or use idle computer time to break them in a few days, with the time-to-break halving every 18 months in either case.
		In general, you shouldn't try to do bulk encryption with elliptic keys; symmetric algorithms are much faster and are better-tested for the job.
		Don't depend on the encryption also providing integrity - an attacker may be able to change the bits into a different value, and although the attacker may not be able to change it to a specific value, merely changing the value may be enough.

		For bulk encryption, HPC can be used with a 512-bit blocksize, taking only 623 clocks/block, or 1.22 clocks/bit.
		Some authors defined realistic encryption tasks that amortized key-setup over a reasonable amount of encryption work, and concluded that key-setup time was irrelevant to the speed rankings.
		I mentioned several uses in my AES1 talk: it replaces CBC, allowing parallel encryption and decryption; it prevents the various splicing attacks that CBC is prone to; it allows random access edits in the middle of a database without chaining-matchup problems from adjacent records.

		It is better suited to bulk encryption of large amounts of data.
		Khufu is a Feistel cipher with 16 rounds by default (other multiples of eight between 8 and 64 are allowed).
		However, Khafre probably requires a greater number of rounds to achieve a similar level of security as Khufu, making it slower at bulk encryption.

		For encrypting bulk data, the ECB or CBC modes are used; for stream data, the CFB or OFB modes.
		It is optomised for bulk data encryption (since key changes are slow), and uses four large 8*32 bit random substitution boxes generated from the supplied key, whose outputs are combined using addition and xor.

		Both the layer 3 IPSec approach and the layer 4/5 SSL acceleration approach represent a grand departure from the 30-year-old history of encrypting bulk data files, a method that might be considered a physical layer (PHY) approach to enciphering bits during transmission.
		Encryption in the commercial world was a hit-and-miss affair until the federal government proposed the data encryption standard (DES) in the mid-1970s.
		These public-key systems allowed the encryption key of a user to be published in the open, since decryption keys could only be determined from encryption keys through various difficult factoring operations.

		When the ciphertext is passed back through the encryption algorithm with the same key applied (as was used for the encryption process) then the plain text is recovered.
		There is actually a shared secret between the encryption and decryption keys; that is, the keys are generated as different components of a common algorithm.
		Further, the public key encryption and decryption operations being discussed are (for purposes of the current discussion) intended to authenticate identity, not assure privacy.
