Abstract

The invention provides a safe data transmission method, device and system. The method comprises the steps that registration information is sent to a robot trusted mechanism; a quintuple, a first public key PK, a hash function and a first private key corresponding to the data sending node P sent by the robot trusted mechanism are received; a shared key between the data sending node P and the data receiving node D is obtained; signature encryption processing is carried out on the shared key KP-D to obtain an encrypted ciphertext of the shared key shown in the specification; 15) the data sendingnode P uses the shared key KP-D and uses an AES encryption algorithm to encrypt the current message M to obtain a ciphertext CT=Encrypt(PK,M,T) of the current message; and 16) the data sending node Psends the ciphertext CT of the current message and the encrypted ciphertext of the shared key shown in the specification to the data receiving node D. By applying the embodiment of the invention, thedata overhead can be reduced.

Description

technical field [0001] The present invention relates to a data security method, device and system, in particular to a data security transmission method, device and system. Background technique [0002] The solution based on the private key mainly adopts AES (Advanced Encryption Standard, Advanced Encryption Standard) to encrypt data and use MAC (Message Authentication Code, message authentication code) to authenticate data. Typical examples based on private key encryption include literature: [1] Raazi S M K R, Lee H, Lee S, et al.
