Wide-Band Optical Frequency Hopping Using Digital Chaos

A wide-band optical frequency hopping (FH) scheme is proposed and analyzed using hyper digital chaos, where the chaotic sequences are applied to encrypt the original data in physical layer during transmission. The multi-fold data encryption is achieved based on the dynamic generation of the optical...

Summary:A wide-band optical frequency hopping (FH) scheme is proposed and analyzed using hyper digital chaos, where the chaotic sequences are applied to encrypt the original data in physical layer during transmission. The multi-fold data encryption is achieved based on the dynamic generation of the optical carrier frequency, FH rate as well as the available frequency set respectively. A hyper digital chaos is used to generate the multiple, independent chaotic sequences for the proposed data encryption, as a result, a huge key space of 10 58 is provided to enhance the security. The performances of data transmission and security enhancement against various attacks are evaluated in details.
