Abstract

While the needs for VoIPs(Voice over IP) encourage the commercial trials for VoIP services, there are many problems such as user authentication, blocking of illegal user and eavesdropping. In this paper, a management algorithm of registration of VoIP terminals is explained and security methods for tolling and data encryption module is designed and built up. The module structure will have the advantages of the entire development of secured gatekeeper without whole modification of gatekeeper. In order to secure the ordinary gatekeeper based on H.323 standard, user authentication and data encryption technologies are developed based on the H.235 standard and simply located over the plain H.323 stacks. The data structures for secured communications are implemented according to ASN.1 structures by H.235.
