Title: Rapid encoding or decoding of large data quantities - by using chip card contg. two codes and using double encoding and decoding to preserve card security
Inventor: LASSMANN GUNTER
IPC: H04L9/06
Filed: 1991-03-07
Abstract: The appts. is used for encoding and decoding large quantities of data. It uses a chip card without losing use of a distinguishing second code K2 of the card which contains two codes.

The server encodes a special first block, sends it to the card and receives it back encoded with K2. The server encodes each block with a value from the preceding block and encodes each block from the card again with K2. The doubly coded block replaces the corresp. singly encoded block in the text. A reverse decoding process is also described. USE/ADVANTAGE - The method enables large quantities of data to be encoded and decoding without the chip card compromising its security
