Design of a Real-name WeChat Portal Based on RSA and MD5 Signature

To solve the problem that traditional WeChat applications can not provide comprehensive service for campus users based on their real identities or roles, a real-name WeChat portal with RSA and MD5 signatures was proposed to satisfy the mobile users in university campus. In this portal, a mechanism about binding OpenID of WeChat and NetID of CAS (Central Authentication System) was designed to realize the real-name identity authentication. To protect the private information, RSA and MD5 signatures were utilized during data transmission. To provide the comprehensive one-site services, all the campus service data used by portal were integrated based on the related campus systems. After testing and running this system in two months, the statistic reports show that it can provide comprehensive one-site service and cross-platform service to mobile users by the WeChat clients installed in their mobile devices. Meanwhile mobile users can also access the private data based on their identities after binding their WeChat accounts and CAS accounts.
