cipher mode

Care must be taken in these cases to select an appropriate Block cipher modes of operation, however.

If the cipher mode does not properly randomise the input, the limit is even lower.

The methods resemble the block cipher modes of operation usually used for encryption.

The MS immediately switches to cipher mode using the A5 encryption algorithm.

Block ciphers can be used as stream ciphers; see Block cipher modes of operation.

IAPM was the first cipher mode created to provide both authentication and privacy in a single pass.

In order to encrypt or decrypt data, use the standard block cipher mode of operation on all but the last two blocks of data.

It is mandatory for this cipher mode to be implemented in any SRTP-compatible system.

Different block cipher modes of operation can have significantly different performance and efficiency characteristics, even when used with the same block cipher.

Stream ciphers, such as RC4, are vulnerable to a bit-flipping attack, as are some block cipher modes of operation.

Electronic codebook and cipher-block chaining (CBC) mode are examples of block cipher mode of operation.

In both cases, since the Air Interface is now in cipher mode, the TMSI is not compromised.

There are two cipher modes defined which allow the original block cipher AES to be used as a stream cipher:

This simplest way of using CFB described above is not any more self-synchronizing than other cipher modes like CBC.

Authenticated Encryption (AE) is a block cipher mode of operation which simultaneously provides confidentiality, integrity and authenticity assurances on the data.

Block cipher modes operate on whole blocks and require that the last part of the data be padded to a full block if it is smaller than the current block size.

For example, the LUKS encryption system includes metadata which detail the block cipher and block cipher mode used in encryption.

Block cipher modes for symmetric-key encryption algorithms require plain text input that is a multiple of the block size, so messages may have to be padded to bring them to this length.

Along with CBC, CTR mode is one of two block cipher modes recommended by Niels Ferguson and Bruce Schneier.

Authenticated Encryption with Associated Data (AEAD) is a class of block cipher modes which encrypt (parts of) the message and authenticate the message simultaneously.

It appears the same diagram is used in Alberto Grand's 'Block Cipher Modes of Operation and the CMAC Mode for Authentication'.

Recommendation for Block Cipher Modes of Operation: The XTS-AES Mode for Confidentiality on Storage Devices nist-sp-800-38E.

In principle any block-oriented block cipher mode of operation can be used, but stream-cipher-like modes can already be applied to messages of arbitrary length without padding, so they do not benefit from this technique.
