Problems solved by technology
[0003] However, there are some problems in communication at present. The existing dynamic library calls are all completed in the host computer, and the memory capacity of the host computer is limited. This leads to memory leaks when the host computer directly calls the dynamic library of the card machine, and communication is easy. Crash, and when the card machine returns data, the speed is also very slow, which affects the program timeout judgment

The invention relates to a method for performing communication by adopting a separated encryption server, which comprises the following steps that: S1, an upper computer and the encryption server as well as the encryption server and a card machine are respectively connected and started, and the encryption server and the upper computer are separately designed; and S2, the upper computer encrypts a plaintext through the encryption server and the card machine, forms a ciphertext, sends the ciphertext to the meter, receives information fed back by the meter, decrypts the fed back information through the encryption server and the card machine, and realizes communication between the upper computer and the meter. According to the method, the communication rate and the security are improved.
Description
technical field [0001] The invention relates to the technical field of electric meters, and in particular, to a method for communicating by using a separate encryption server. Background technique [0002] At present, the encrypted communication of electric energy meter 698 protocol has been popularized and applied in the national grid. The market has higher and higher requirements for the communication success rate of electric energy meters, and the functional requirements of electric energy meters are more and more complicated. In recent years, the new standard protocol for smart energy meters has been released and updated rapidly. In order to meet the needs of communication security, new functions of power supply bureaus, or manufacturers' research and development of new products and repairing defects, it is an inevitable trend for manufacturers to test ESAM to achieve local encrypted communication. The standard remote communication process requires the 698 backend to sup...
