Key Remote Sharing Simulation of Multiple Secure Domain in Wireless LAN
To ensure the secure transmission of network information,this article put forward a key sharing method across multiple security domains in WLAN.Firstly,based on the analysis of cross-domain access forms in LAN,as well as cloud computing method and trust mechanism,the expected value of access credibility for cross-domain access applicants was calculated to achieve the risk assessment of user's cross-domain access behaviors.Secondly,a key sharing strategy was introduced to initialize the important information,generate subkeys and permission certificates,and reconstruct keys.Moreover,the key recombination and distribution among group members were implemented,while completing the encryption of information.Finally,we achieved the remote key sharing among group members.The experiment results prove that after the important information encrypted by the proposed method,the information hiding level is higher in addition,the method has excellent anti-attack capability,which is of great significance for the storage and transmission security of information.
