A number of mechanisms are described that can be used in the design of a protocol converter for authentication and key distribution protocols. First, the scope of the mechanisms is defined. The authors outline the class of authentication systems that were considered during the design of the mechanisms. A first mechanism, based on proxies and a synchronization protocol, allows for a transparent protocol conversion. It is generic, and can be tailored to different specific situations. The second mechanism addresses the problem of the state of the protocol converter. Both mechanisms can be used separately or in combination. When properly combined, they provide for a robust, transparent, and safe protocol converter for authentication and key distribution protocols. Example applications are described in some detail. >
