Encryption Scheme of Wireless Communication in Missile Launch Control System Based on DES Algorithm

Aiming at the problems of information disclosure when the wireless communication is applied to the missile launch control system, an encryption scheme based on DES algorithm is proposed. The scheme adds redundant code in sending data, which ensures the reliability of encryption. It uses random identification code in received data to effectively hide the data structure of ciphertext, and provides support in data recovery at receiving end. Analysis shows that the scheme is easy to implement and good in security, suitable for use in missile launch control system.
