chained block encryption
chained block encryption[¦chānd ′bläk in′krip·shən]
The use of a block cipher in which the bits of a given output block depend not only on the bits in the corresponding input block and in the key, but also on any or all prior data bits, either inputted to or produced during the enciphering or deciphering process. Also known as block chaining.
