In order to improve the information security of ship communication, the design of ship security information system. This paper puts forward a design method of ship security system based on elliptic curve cryptography, information encoding using binary bit sequence modulation method for ship secret information transmission, according to the structure of Turbo code encryption and decryption keys, the use of elliptic curve cryptosystem constructed for secure communication protocol. Under the embedded Linux kernel, the encryption algorithm is used to realize the optimal design of ship security system. The simulation results show that the method can be used to secure the ship communication, the data encryption is better, the ability of resisting attack and interference is strong, and the security of data information is improved.
