The invention discloses a method and system for determining a physical layer authentication threshold, and relates to the technical field of information security; the method specifically includes: in the first time slot of S1, the legal sender A sends the first data frame to the legal receiver B, and the first The data frame is authenticated by the upper layer; S2. Extract the physical layer authentication "fingerprint" of the legal sender A, and store it in the memory of the legal receiver B; S3. Select an initial threshold; S4. In the next time slot, the sender X sends the second data frame to legal receiver B, and extracts the physical layer authentication "fingerprint" of sender X; S5. Sets the physical layer authentication "fingerprint" sample; S6. Extracts the "fingerprint" sample and the current data frame "fingerprint" Test statistic; S7. observe the current state, select the next threshold according to the greedy strategy; S8. carry out physical layer authentication by comparing the size of the test statistic and the threshold; the present invention has low complexity and can be used in the state of unknown channel statistics Get the physical layer authentication threshold.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for determining a physical layer authentication threshold. Background technique [0002] With the rapid development of the mobile Internet, micro-terminal devices are widely used in resource-constrained environments such as cellular networks, sensor networks, and the Internet of Things. Or fail node identification and other security measures. Due to the shortage of computing and storage resources, micro-terminal devices are faced with the problem that traditional security technologies are not applicable, and it is difficult to support classic cryptographic algorithms, and authentication algorithms based on classic passwords have higher computational complexity than encryption algorithms. Especially in future 5G communications, the need for dense node applications, low latency, and high-security access is proposed. When there are many nodes, it is...
