WebMar 15, 2024 · I received a requirement to implement encryption with AES-CTR with a 128-bit key and 128-bit IV. ... "So using the nonce and the counter exactly the same way is crucial, right?". Yes, of course. AES-CTR, regardless of the key size, uses a 128-bit block size and that is always the size of the initial counter block. Along with CBC, CTR mode is one of two block cipher modes recommended by Niels Ferguson and Bruce Schneier. CTR mode was introduced by Whitfield Diffie and Martin Hellman in 1979. CTR mode has similar characteristics to OFB, but also allows a random-access property during decryption. See more In cryptography, a block cipher mode of operation is an algorithm that uses a block cipher to provide information security such as confidentiality or authenticity. A block cipher by itself is only suitable for the secure … See more The earliest modes of operation, ECB, CBC, OFB, and CFB (see below for all), date back to 1981 and were specified in FIPS 81, DES Modes of Operation.
