Abstract: The present application discloses a multi-encryption based data transmission method. Compared with the prior art, the present application uses triple-hybrid encryption. When data is transmitted each time, plaintext data is encrypted by an asymmetric encryption method, and the data transmission random number plaintext is encrypted by a symmetric encryption method. A signature is added to the transmitted data. Once the signature is found to be inconsistent, it can be inferred that there is an illegal attacker, and random numbers generated each time are different from each other, and are doped inan encrypted message, so the attacker is difficult to determine the specific ciphertext length and a location of the specific encrypted message, and cracking and reuse cannot be achieved, thereby effectively resisting replay attacks and ensuring the confidentiality and authenticity of the data transmission. In addition, the present application also uses the hash value contrast method to ensure the integrity of the transmitted data.
