  • Apparatus for and method of overhead reduction in a block cipher
    Patent number: 6249582
    Abstract: An apparatus and method for reducing the overhead of a block cipher includes shortening the length of the initialization vector so that its length is less than the length of each block of information processed by the block cipher. The block cipher is utilized in cipher block chaining mode. The shortened vector is loaded into the block cipher with other pseudo-random bits. Cipher block chaining prevents the overall cycle length of the block cipher from decreasing. Thus, channel burden of repeatedly transmitting the initialization vector is reduced because it is shorter, but security is not unduly diminished because cycle length is not diminished. Late entry can be achieved. Also, combination of this method with coasting can increase accurate synchronization even in severely corrupted channels. Security level versus amount of vector shortening can be selected.
