| Abstract: | To solve the bottle-neck on high speed and real-time information transmission, a publickey cryptosystem based on cellular automata is proposed. This algorithm employs n one-dimensional reversible cellular automata as a secret key, and the two-dimensional Moore-neighbor irreversible cellular automata constructed by the cellular automata is taken as a public-key. Both of these keys compose the public-key cryptosystem. This algorithm is simple and is easy to be implementated with VLSI, which efficiently solves the bottle-neck phenomenon caused by the complicated encryption algorithm during the high-speed and real-time information transmission. |
| Keywords: | encryption algorithm public-key cryptosystem cellular automata real time |
