- Abstract
Two remote sensing image encryption algorithms based on the randomness of audio channel sequences are proposed and their robustness is verified by many attack experiments. The first encryption algorithm uses the randomness of audio to encrypt image pixels in RMD. Compared with traditional image encryption algorithms, this algorithm has high randomness and security and can resist stronger password attacks. However, the encryption algorithm takes a long time. Considering that information sometimes needs to be transmitted urgently, a second encryption algorithm is proposed. By combining vocal tract and random phase to form new public and private keys, the number of computation amount and dislocations is reduced. The second algorithm is short in time but low in security.
