Recognized to be the unique 256-bit block encryption
algorithm that possesses security levels and processing abilities comparable to AES - BestCrypt's default option - the Camellia cipher can easily be selected when creating a new container.
A new mode of operation for block encryption
called plaintext feedback XORing (PFX) is presented in .
The specification called as symmetric algorithm (same key for encryption and decryption) using block encryption
(see block cipher) of 128 bits in size, associate key sizes of 128, 192 and 256 bits, as a smallest.
A block encryption
method registered as United States Department of Commerce Federal Information Processing Standard FIPS PUB197.
 for block encryption
. In addition, the concept of Reversible cellular automata (RCA) has also been discussed by Xia et al.
In this paper we will propose a novel and practical quantum block encryption
algorithm based on a quantum shift register.
Therefore, EPPA can be considered as a block encryption
algorithm operating on these groups of bits with an unvarying transformation that is specified by a symmetric key.
[6.] Matsui, M.: New Block Encryption
If a new cipher key ([K.sub.in]) is received, the round key computation mechanism is activated for the first counter block encryption
. Simultaneously, the round keys ([K.sub.r]) are cached in their corresponding registers pointed by the address generator.
This is the most standard block encryption
algorithm today, as indicated in FIPS PUB 197.
Another method is with block encryption
, which is where a message is broken up into blocks and each block receives a separate encryption algorithm.
