Information sharing key security detection based on PKG trust gateway
Due to the increasing variety of intrusion behaviors,which pose a serious threat to network security,a security detection method for information sharing keys is proposed after establishing a PKG trust gateway model.After preprocessing the data,the authentication methods of PKG trust gateway for nodes under two different forms of network access are analyzed.Nodes can only access the network after passing the authentication.The PKG trust gateway sends the shared key and the verification value between the newly accessed nodes through a key chain,and judges whether the shared key has been tampered with or attacked by comparing the verification value.If the verification value is different,it indicates that the shared key has been attacked,and reports the attacked key to the PKG trust gateway;if the verification values are the same,it indicates that the shared key has not been attacked and can be decrypted to obtain the session key.Through relevant experimental tests,the proposed method can achieve accurate detection for different types of intrusion behaviors,while ensuring the highest detection efficiency and the lowest false detection rate.
