Abstract
This paper proposes an optical encryption and decryption system for OFB(Output Feedback Block) encryption algorithm. The proposed scheme uses a dual-encoding technique in order to implement optical XOR logic operation. Also, the proposed method provides more enhanced security strength than the conventional electronic OFB method due to the huge security key with 2-dimensional array. Finally, computer simulation results of encryption and decryption are shown to verify the proposed method, and hence the proposed method makes it possible to implement more effective and stronger optical block encryption system with high-speed performance and the benefits of parallelism.
