The invention discloses a method, system and equipment for secure data transmission between a terminal and an electric energy meter. The method includes: obtaining performance indicators in the communication channel between the electric energy meter and the terminal, establishing a communication channel model; generating a key in the communication channel model , bind the key and data for encryption to obtain encrypted data; generate coded information containing beamforming and artificial noise, allocate transmit power for beamforming and artificial noise in the coded information, and encode the encrypted data according to the allocated transmit power to encode. The invention encodes the encrypted data by using beamforming and artificial noise. The beamforming and artificial noise depend on the randomness of the communication channel. It is difficult for eavesdroppers to crack the beamforming at the transmitter. At the same time, artificial noise can further deteriorate the eavesdropping channel, making it difficult for eavesdroppers to obtain encrypted data.
Description
technical field [0001] The invention relates to the technical field of data transmission security, in particular to a method, system and equipment for secure data transmission between a terminal and an electric energy meter. Background technique [0002] At present, in the power system, the collection terminal is connected to multiple electric energy meters through the power transmission line. In order to ensure the security of the data transmission, the traditional method mainly encrypts the transmitted data through a symmetric key or an asymmetric key. Among them, the symmetric encryption algorithm uses the same key for encryption and decryption, which is more efficient and is mainly used for encrypting data. Asymmetric encryption algorithm, also known as public key encryption algorithm, uses a pair of public key and private key to realize encryption and decryption. It has high complexity and is mainly used for key distribution. However, with the continuous improvement of...
