NIST IR 7298

Block - Sequence of binary bits that comprise the input, output, State, and Round Key. The length of a sequence is the number of bits it contains. Blocks are also interpreted as arrays of bytes. SOURCE: FIPS 197

NIST SP 800-22r1

Block - A subset of a bit string. A block has a predetermined length.

NIST SP 800-38B

Block - For a given block cipher, a bit string whose length is the block size of the block cipher.

NIST SP 800-38C

Block - A bit string whose length is the block size of the [[Term:block cipher algorithm | block cipher algorithm]].

NIST SP 800-38D

Block - For a given block cipher, a bit string whose length is the block size of the block cipher.

NIST SP 800-67v1.1

Block - In this recommendation, a binary string, for example, a plaintext or a ciphertext, is segmented with a given length. Each segment is called a block. Data is processed block by block, from left to right.
