Design and application of a dual-mode carrier communication security universal solution

Abstract： As internet information technology continues to evolve and advance, information security has become increasingly critical. As a next-generation power information communication method, HPLC+HRF dual-mode communication technology has prompted State Grid Corporation of China to impose higher requirements on dual-mode carrier communication modules. The modules must undergo identity authentication through security technologies, with communication information encrypted accordingly. This solution employs a security algorithm coprocessor to handle authentication and encryption/decryption during carrier communication, utilizing high-speed SPI for data transmission. It features coprocessor upgrade capabilities, expanding the security application scenarios for power communication. The solution not only meets State Grid Corporation's security requirements for authentication and encryption/decryption but also satisfies overall dynamic power consumption demands in low-power mode. It has been applied in Smart Chips' self-developed concentrators, Type I and Type II collectors' communication units, as well as single-phase and three-phase meter carrier communication units, distributed across local communication systems in transmission, distribution, and power consumption information collection systems across various provincial grids.
