Key length

Advanced Encryption StandardAdvanced Encryption Standard, a new encryption standard, whose development and selection was sponsored by NIST, that will support key lengths of 128, 192, and 256 bits. FIPS approved cryptographic algorithm that is a symmetric block cipher using cryptographic key sizes of 128, 192, and 256 bits to encrypt and decrypt data in blocks of 128 bits. The encryption standard selected in October 2000 by the National Institute of Standards and Technology (NIST) that is based on the Rijndael cipher.

(1) One digit, usually the last, of an identifying field is a mathematical function of all of the other digits in the field. This value can be calculated from the other digits in the field and compared with the check digit to verify the validity of the whole field. (2) A numeric digit that is used to verify the accuracy of a copied or transcribed number. The numeric digit is typically appended to the end of a number.

A private key cryptosystem published by the National Institutes of Standards and Technology (NIST). DES is a symmetric block cipher with a block length of 64 bits and an effective key length of 56 bits. DES has been used commonly for data encryption in the forms of software and hardware implementation. A standard cryptosystem proposed in 1977 for all government communications. DES and 3DES were superseded by Advanced Encryption Standard (AES) in December 2001. Cryptographic algorithm, designed for the protection of unclassified data and published by the National Institute of Standards and Technology (NIST) in Federal Information Processing Standard (FIPS) Publication 46. (FIPS 463 withdrawn 19 May 2005) (. See Triple DES) and CNSS Advisory IA/0204 Revised March 2005)

Where only two values or states are possible for a particular condition, such as “on” or “off” or “1” or “0. ” Binary is the way digital computers function because it represents data as on or off.

A new version of the SuperFrame that allows for more frames to be grouped together. In a T1 circuit, each of the 24 DS0 channels are sampled every 125 microseconds and 8 bits are taken from each. If you multiply the 8 bits by the 24 channels, you get 192 bits in a chain, and then add one bit for timing, you get 193 total bits in one frame. Twelve frames comprise the SuperFrame. For the Extended SuperFrame, we double the number of frames, making the total 24.
