E-test is that test performed over the internet inwhich questions and solutions are computer files rather thansheets of paper. The application of e-test as a perspectiveknowledge measurement is apparent. But, security for suchscheme is not obvious. Thus in this article we introduce asecure e-test scheme with wireless networks. In addition, wesuggest a swapping technique between test application andtest security. The main contribution of the proposed schemeis to overcoming of the limitations in the milieu trust system.We are claimed that the proposed scheme is efficient andmore flexible than the milieu trust system.
