Abstract
This paper describes a system that controls access to
computer networks through publicly accessible LANs, enabling network
administrators to authorize users either on a permanent or occasional
basis. The system has been designed with minimal assumptions about
the software and hardware required of users, and requires very little
specialized equipment within the network infrastructure. We enumerate
the requirements for such a system, describe the design and
implementation of the system, and note tradeoffs between security and
efficiency.
