In order to improve the security transmission performance of sensitive data of ship wireless mobile communication network under cloud computing,the design of data leakage prevention is carried out.A wireless mobile communication network sensitive data encryption technique based on finite domain hybrid coding is proposed.The method of outlier decomposition is used to decompose the sensitive data of ship wireless mobile communication network by vector quantization.In the data transmission link layer,the encrypted data is randomly scrambled,and the ship network transmission sensitive data is cyclically shifted and randomly linear reorganized in the finite domain,and the key agreement protocol is constructed for hybrid coding.The encryption key and decryption key are constructed and the sensitive data of ship wireless mobile communication network are designed under cloud computing.The simulation results show that the method is used to encrypt the data.The ability of data anti-plaintext attack is stronger,the ability of anti-leakage is improved,and the performance of secure transmission of data is improved.
