By using ASP.NET technology, AJAX technology and Browser / Server mode, designed and implemented an intelligent network test system. Detailed description of the network test system development environment, system components, system functions and key technologies, And problems encountered in the development process, proposed solutions.
This paper describes the concept of XML digital signatures, analyzes the digital signature and the signature verification process, describes the W3C digital signature specification, and studies how to ensure data security in network exam in C #.NET environment. Experiments show that: XML digital signature in network test system ensures the integrity of network data transmission, the identity of verifiability and non-repudiation.
In order to meet the demand of test paper in the network test system, the paper establishes test paper mathematical model, uses the integer coding strategy, and applies the improved genetic algorithm to the auto-generating test paper module. The results of the test show that the algorithm can complete the intelligent test paper well, and improve it effectively. Key words: auto-generating test paper; genetic algorithm; fitness function
