It features firewall to firewall transfers and TLS Encryption support.

This announcement followed a five-year standardization process in which fifteen competing designs were presented and evaluated, before the Rijndael cipher was selected as the most suitable ( see Advanced Encryption Standard process for more details ).

When the Data Encryption Standard cipher was released in 1977, a key length of 56 bits was thought to be sufficient.

On 26 May 2002, DES was finally superseded by the Advanced Encryption Standard ( AES ), following a public competition.

Encryption of data and relaying of requests makes it difficult to determine who inserted content into Freenet, who requested that content, or where the content was stored.

In cryptography, the International Data Encryption Algorithm ( IDEA ) is a block cipher designed by James Massey of ETH Zurich and Xuejia Lai and was first described in 1991.

The algorithm was intended as a replacement for the Data Encryption Standard ( DES ).

IDEA is a minor revision of an earlier cipher, Proposed Encryption Standard ( PES ); IDEA was originally called Improved PES ( IPES ).

* MARS ( cryptography ), a block cipher that was IBM's submission to the Advanced Encryption Standard process.

At the time, the Data Encryption Standard with 56-bit keys was still a US government standard, mandatory for some applications.

Encryption was considered a very sensitive subject and the coming together of delegates from different countries was unheard-of at the time.

The Advanced Encryption Standard ( AES ), the block cipher ratified as a standard by National Institute of Standards and Technology of the United States ( NIST ), was chosen using a process markedly more open and transparent than its predecessor, the aging Data Encryption Standard ( DES ).

The Advanced Encryption Standard ( AES ) candidate RC6 was based on RC5.

It was designed by Ron Rivest, Matt Robshaw, Ray Sidney, and Yiqun Lisa Yin to meet the requirements of the Advanced Encryption Standard ( AES ) competition.

A widely-used and previously-developed cryptographic mechanism is the Data Encryption Standard, which was used primarily for the protection of electronic funds transfers.

* Serpent ( with Ross Anderson and Lars Knudsen ), a block cipher which was one of the final five contenders to become the Advanced Encryption Standard

Lucifer was a direct precursor to the Data Encryption Standard.

Serpent is a symmetric key block cipher which was a finalist in the Advanced Encryption Standard ( AES ) contest, where it came second to Rijndael.

The original Serpent, Serpent-0, was presented at the 5th workshop on Fast Software Encryption, but a somewhat tweaked version, Serpent-1, was submitted to the AES competition.

One of their joint projects resulted in the algorithm Rijndael, which in October 2000 was selected by the National Institute for Standards and Technology ( NIST ) to become the Advanced Encryption Standard ( AES ).

In 1975-76, Diffie and Martin Hellman criticized the NBS proposed Data Encryption Standard, largely because its 56-bit key length was too short to prevent Brute-force attack.

The last official version of NetPositive before the Be, Inc. bankruptcy was 2. 2 / 2. 2. 1 for US customers, but there also exists a 3. 0d3 beta version, and a leaked 2. 2. 2 which changed from the RSA Encryption Engine to OpenSSL, possibly indicating that Be were cleaning the source of commercial code with an intent to open source, like the OpenTracker project.

Encryption is provided using the SSL / TLS protocol-layer, either in the traditional always-on mode used by HTTPS or using the HTTP Upgrade extension to HTTP ( RFC 2817 ).

Similar errors had been made by the developers of the UK's terrestrial digital Xtraview Encryption System, which provided no encryption and relied on hiding channels from listings.

The Advanced Encryption Standard ( AES ) is a specification for the encryption of electronic data established by the U. S. National Institute of Standards and Technology ( NIST ) in 2002.

The Data Encryption Standard ( DES, or ) is a previously predominant algorithm for the encryption of electronic data.

* Eiffel Encryption Library: Open source cryptography library for the Eiffel language

Encryption is also used to protect data in transit, for example data being transferred via networks ( e. g. the Internet, e-commerce ), mobile telephones, wireless microphones, wireless intercom systems, Bluetooth devices and bank automatic teller machines.

Encryption, by itself, can protect the confidentiality of messages, but other techniques are still needed to protect the integrity and authenticity of a message ; for example, verification of a message authentication code ( MAC ) or a digital signature.

For instance, standards for encoding data, e. g., country codes, but more significantly some encryption standards, such as the Data Encryption Standard ( FIPS 46-3 ) and the Advanced Encryption Standard ( FIPS 197 )

* Encryption Policy: Memo for the Vice President CIA memo to Al Gore on suggested US policy on key recovery, 11.

In cryptography, Triple DES is the common name for the Triple Data Encryption Algorithm ( TDEA or Triple DEA ) block cipher, which applies the Data Encryption Standard ( DES ) cipher algorithm three times to each data block.

Encryption algorithms which use the same key for both encryption and decryption are known as symmetric key algorithms.

Encryption for e-mail had already been in use for some time but is now the renewed focus of internal security practices for sending e-mail containing patient information.

There are techniques for creating ciphers on unusual or fractional block sizes ( i. e. domains whose size is not a power of two ); see Format-Preserving Encryption.

In cryptography, SEAL ( Software-Optimized Encryption Algorithm ) is a very fast stream cipher optimised for machines with a 32-bit word size and plenty of RAM.

IBM submitted the Feistel-network version of Lucifer as a candidate for the Data Encryption Standard ( compare the more recent AES process ).

* Encryption and / or authentication of documents ( e. g., the XML Signature or XML Encryption standards if documents are encoded as XML ).

This approach of alternatively applying substitution and permutation transformation has been used by IBM in the Lucifer cipher system, and has become the standard for national data encryption standards such as the Data Encryption Standard and the Advanced Encryption Standard.

Direct broadcast satellites and digital cable services, because of their digital format, are free to use more robust security measures such as the Data Encryption Standard ( DES ) or the RSA and IDEA digital encryption standards.

* XML Signature and XML Encryption, two other W3C standards used by the XKMS protocol.
