| Along with the social informatization level gradually improve, more and more business and work are included in the information management. For the cases with a common vocational college in Shaanxi province, using SSO, information bearing by QR code, LDAP directory service and symmetric and asymmetric encryption to decryption technology create a SSO solution, solving problem such as system high maintenance cost and low safety triggered by systems are weakly related. This paper studied the single sign on system, the main research harvests are as follows:According to the actual situation of the different application system in Higher Vocational Colleges, this paper has analyzed background and significance of the SSO, introduces the single sign on system and the technical knowledge required, provides two kinds of practical solutions for SSO, and then make a summary to the domestic and foreign development level. In additional complete demand analysis of single sign on in higher vocational college, presents a design conception and the establishment of the system model, proposed a complete system solutions of single sign on.In the process of design for single sign on system, this paper introduces the QR code information fast exchanging and asymmetric key system, realizes user authentication without password, which can not only improve the work efficiency, but also reduce the security hidden danger for user in password generation, memory, input and other aspects. The system is developed based on Windows Server 2003, Android4.5 and IOS7 operating system, including server and mobile terminal. The system is composed of modules, each module coordination work, provides the following services: login all system in single point, automatic generation submission, destruction and reset the identity signature, information encryption, data access interface for new system.Finally, the system is tested by test case with black box testing, result says the system can complete the system design goal, and meet the specific needs of user, can guide and promote other higher vocational colleges to integrate information. |
