With the advance of computer and communication technologies, a lot of organizations operate virtual universities that provide learning environments out of temporal and spacial constraints. And many research works on the web-based virtual universities where learner-centered, situated learning, and problem-centered learning are fulfilled have been proposed. Various tech- niques are required to build the virtual universities efficiently. Among them, security is considered as an important skill in the virtual universities. In this paper, when a web-based virtual university is implemented, the certification technique for the virtual university is presented, And a method for con- structing a certificate system to support the virtual university is also pre- sented.
