Because of the defect of only the single data encryption and the use of famous encryption algorithm, which was not improved in traditional methods of the registration process, a combined encryption algorithm is proposed in this thesis. That is, the algorithm security is greatly improved, through researching several famous data encryption algorithms, and improving some data encryption algorithms, and arranging encryption algorithms in some order.
Finally, the combined encryption algorithm is successfully made by using the initial encryption algorithm, Micro Genard encryption algorithm and the famous Base64 encryption algorithm. That is, in accordance with the order of the initial encryption algorithm, the improved Micro Genard encryption algorithm and the famous Base64 encryption algorithm, the
user’s information is gradually encrypted, and the algorithm security is greatly enhanced. Besides, to video surveillance software system for instance, which is widely used in the field of the traffic security management, the combined encryption algorithm is completely validated, and its security is very high.
