Data transmission safety authentication method and system based on edge calculation and vector projection

Abstract

The invention discloses a data transmission safety authentication method and a data transmission safety authentication system based on edge calculation and vector projection. The method comprises thefollowing steps: S1, initial authentication: when a terminal node performs data transmission with an edge computing server, the edge computing server performs upper-layer authentication on an initialdata packet, and extracts a corresponding channel information vector as a reference vector for data packet authentication; S2, calculating the vector projection of the channel information: when the edge calculation server receives a new continuous data frame, extracting the channel information of the current data frame and calculating the vector projection of the channel information correspondingto the previous frame of data packet; and S3, judging the legality of the continuous data frames: checking the legality of the continuous data frames through binary hypothesis. According to the invention, the calculation complexity of the edge calculation server is reduced, and the safety and the data authentication rate of the system authentication data are improved.

Description

technical field [0001] The invention relates to security authentication protection of data transmission, in particular to a data transmission security authentication method and system based on edge computing and vector projection. Background technique [0002] With the rapid development of Internet of Things technology, various terminal devices are widely used in daily life and work, and will generate massive amounts of data. The traditional cloud computing system can no longer meet the practical needs in terms of matching massive edge data, real-time control, network traffic load, cloud data privacy and security, and the emerging edge computing technology that performs calculations on the edge of the network can just provide IoT devices with Edge intelligence services. By building small edge data centers and micro-cloud data centers, some or all of the computing tasks of the original cloud computing model are migrated to edge servers, which can not only reduce the computin...

Problems solved by technology

[0003] The high strength of traditional cryptography-based data security and privacy protection faces high computational complexity, which makes it difficult to adopt terminal nodes with limited energy and computing capabilities, and the computing resources of edge computing servers are far inferior to cloud computing systems. In the face of numerous nodes and massive data, traditional cryptography-based data security and privacy protection can no longer meet practical needs
