A Lightweight Identity Authentication and Platform Identification Evaluation Method

Abstract

The invention discloses a light-weight identity authentication and platform identification evaluation method, which includes the following steps: Step 1, when the AR accesses the network for the first time, the PM verifies the platform identity certificate and private identity certificate of the access requester AR and the access controller AC. Key signature, if the verification is passed, go to step 2, otherwise re-verify; step 2, conduct the first platform credible authentication evaluation, if the evaluation is successful, the access requester AR saves the hash value M of the platform configuration information of the access controller AC AC , the controller AC saves the hash value M of the platform configuration information of the access requester AR AR , execute step 3, otherwise it is determined that the platform is untrustworthy; step 3, when the access requester AR needs to access the network again, implement a lightweight identity authentication method, if the authentication is successful, execute step 4, otherwise do not access the network; step 4 , implementing a lightweight platform trustworthiness identification and evaluation method for platform trustworthiness identification and evaluation.

Description

technical field [0001] The invention relates to a lightweight identity authentication and platform identification and evaluation method. Background technique [0002] When a mobile terminal accesses the network through a mobile communication network, air interception and eavesdropping may pose a serious threat to the transmitted sensitive information. Cyber ​​attacks, causing security threats. In order to ensure the security of terminals accessing the network, the Trusted Network Connection Architecture (TCA) has developed an identity authentication protocol and a platform authentication evaluation protocol to ensure that the information sent by the terminal accessing the network is credible and there is no The attacked terminal may provide false information. [0003] However, the TCA protocol communicates frequently and requires a large amount of calculation. It needs multiple rounds of calculation, data interaction and verification to complete. It requires high network q...
