The invention discloses a physical layer authentication method based on mixed frequency hopping and channel phase response, and aims to improve authentication performance under various attack strategies. According to the technical scheme, frequency hopping (FH) is introduced in the authentication process, and a frequency hopping mode is generated through nonlinear transformation based on a timestamp and a shared key, so that it is ensured that the carrier frequency used in each authentication process changes randomly. Eve is difficult to effectively carry out interference attack or passive attack on the correct carrier frequency. Furthermore, in consideration that the time-varying characteristics of the wireless channel may not be well matched, particularly for some quasi-static channels, the FH may provide fast time-varying characteristics as the carrier frequency is updated during different authentication processes. According to the method, the anti-interference capability of the system is improved, so that a legal user can still keep a relatively high authentication success rate under interference attack.

Compared with the prior art, the application has the advantages of improving the anti-interference ability and the accuracy, etc.

The present application proposes a single sign-on authentication method, device, electronic device and storage medium, wherein the method comprises: after receiving a login authentication request of a first application to be jumped sent by a terminal device, including the security level of the first application, the first signature, the first user identifier, and the first relationship index of the first application associated with the first user identifier, in the case where the first signature is successfully verified, an authentication strategy is determined based on the security level of the first application, and the authentication strategy and the association relationship corresponding to the first application in the login registration table are used to verify the first relationship index and the first user identifier to determine the authentication result, and the authentication result is sent to the terminal device. This improves the reliability of single sign-on authentication and expands the application scenarios of the single sign-on authentication method.

The invention relates to the technical field of identity authentication, in particular to an authentication system based on identity authentication and used for intelligent home remote monitoring. The system comprises a verification evaluation unit, a remote monitoring unit, a communication encryption unit and an optimization decryption unit. According to the invention, the length comparison module derives the symmetric encryption key from the calculated shared key of the intelligent lock, and then counts the length of the symmetric encryption key according to the derived symmetric encryption key; according to the method, the key length of the symmetric encryption is compared with the key length of the symmetric encryption in the set standard key length range, and then the key length of the symmetric encryption is intercepted, so that the calculation complexity can be reduced by controlling the key length, the key length is greatly reduced, and the calculation efficiency is improved. According to the technical scheme, the response speed of the intelligent lock can be remarkably improved, so that smoother user experience is provided, meanwhile, the short key length is used, needed computing resources are greatly reduced, computing resource consumption can be reduced, and the performance of the intelligent lock is improved.
