Logistics System-oriented Unified Autentication And Authorization Of Cloud Computing

Because cloud computing has the advantages of on-demand service, broad network access andrapid flexibility,traditional application systems continually migrate to the cloud platform，thusbrings massive access authentication request and complex user rights management and drives thecontinuous development of authentication. With the popularity of cloud computing, a large numberof sensitive user data is stored in the cloud, Once the user’s identity is stolen, It is likely to causedisclosure of privacy and sensitive data and cause huge losses to the user or enterprise.Traditional authentication technology cann’t meet the security needs of the user, this paperproposes the unified authentication and authorization mechanisms of the cloud computing which islogistics-oriented,presents a unified authentication and authorization framework on the basis ofrelated study.This framework use LDAP(Lightweight Directory Access Protocol) as the store centerfor the user’s personal information.The LDAP is responsible for storage and access controlmanagement of personal information.Each of the authentication modules of the unifiedauthentication system is analyzed，the authentication modules include authentication for cloudplatform,authentication for cloud application systems and authentication for end-users who useremote virtual machine.In order to verify the unified authentication and authorization framework mentioned above，thispaper use OpenStack which is open source cloud computing platform to build cloud platforms toverify the authentication for cloud platform. In oder to verify the athentication of cloud applicationsystems, this paper use CAS which is for SSO to verify the authentication of logistics applicationsregarded as cloud application systems. Use Spice as remote desktop access protocol to verify theautentication which is aim at end-users who are accessing the remote virtual machine.In summary, Through the study of cloud computing unified authentication and authorizationmechanisms,this paper analysed and verified the authentication and authorization of users in cloudcomputing and has a certain significance for the development of the cloud computingauthentication.
