This paper proposed a new Secure Parallel Cipher Block Chaining (SPCBC) mode of operation that provides enhanced security over the current modes.
7814-W implements the Electronic Codebook and the Cipher Block Chaining modes of operation for both encryption and decryption, and supports key sizes 128 bit, 192 bit, and 256 bit.
For some methods, such as DES operating in the Electronic Code Book (ECB) mode or DES in the Cipher Block Chaining (CBC) mode, the consequences of lost cells are small on data, voice and video communications (for these modes, one additional cell at most is affected for a lost cell).
