A Secure Channel Service Based on Multi-connection Communication in Power System

The security of data transmission has become more important in modern network communications in new power system. In order to guarantee the secure and reliable communication of power load management terminals under the new power system, this paper proposes a Secure Channel Service based on multi-connection communication. With the multi-connection feature, we divide the data into multiple slices and encrypt each slice before transmitting it over a plurality of connections. Meanwhile, this paper proposes a simple and efficient encryption algorithm for transmitted data that utilizes the multi-connection feature to ensure the simplicity and efficiency of the transmission computation and processing without generating a large amount of key data. Using time-slot scheduling strategy and multi-connection strategy as the main strategy and slice encryption strategy as the auxiliary strategy, the proposed Secure Channel Service can satisfy the requirements of higher level of secure data transmission of power load management terminals.
