Safe Data Transmission of Substation Wireless Sensor Internet of Things Gateway Based on WAPI Technology

Abstract:Due to the continuous updating and upgrading of network attack means, the data transmission security problem of substation wireless sensor internet of things is becoming more and more serious, which directly threatens the operation stability of substation and power system. Therefore, a research on the data transmission security method of substation wireless sensor internet of things based on WAPI technology is proposed. Based on WAPI technology, a secure transmission framework of substation wireless sensor internet of things data is constructed. On this basis, a two-way identity authentication mechanism is formulated, and the key negotiation process is determined, so that UE and AP can obtain the same encryption key. The gateway data is encrypted and decrypted by combining SM4 algorithm in WAPI technology, thus realizing the secure transmission of substation wireless sensor internet of things data. The test results show that the maximum throughput achieved by the proposed method is 10400 kB/s, the minimum packet loss rate is 1%, and the maximum anti-attack ability factor is 9.5, which fully proves that the proposed method has a higher level of data transmission security.
