Plaintext Block

Some articles on block, plaintext block, blocks, plaintext:

Initialization Vector - Motivation
... A block cipher is one of the most basic primitives in cryptography, and frequently used for data encryption ... However, by itself, it can only be used to encode a data block of a predefined size, called the block size ... For example, a single invocation of the AES algorithm transforms a 128-bit plaintext block into a ciphertext block of 128 bits in size ...
Ciphertext Stealing - General Characteristics
... Ciphertext stealing is the technique of altering processing of the last two blocks of plaintext, resulting in a reordered transmission of the last two blocks of ciphertext and no ciphertext ... This is accomplished by padding the last plaintext block (which is possibly incomplete) with the high order bits from the second to last ciphertext block (stealing the ... The (now full) last block is encrypted, and then exchanged with the second to last ciphertext block, which is then truncated to the length of the final plaintext block, removing ...

Famous quotes containing the word block:

    Being dismantled before our eyes are not just individual programs that politicians cite as too expensive but the whole idea that society has a stake in the well-being of children down the block and the security of families on the other side of town. Whether or not kids eat well, are nurtured and have a roof over their heads is not just a consequence of how their parents behave. It is also a responsibility of society—but now apparently a diminishing one.
