Abstract: Web-based distance testing system brings out a series of security problems. The security of Web-test includes not only normal information security problems like authentication. privacy, access control, integrality, etc, but also unique ones such as cheat-preventing, paper-protecting, etc. We suggest a half-closed Web-test environment, and use a particular testing gateway to apply security mechanism. The functions and running process of the testing gateway is also presented in detail.
