Traditional access control mechanisms focus on separating users from one another and are designed with the assumption that there is a competent systems administrator or security manager controlling who may do what. These mechanisms are inappropriate for personal digital assistants (PDAs) where there is a single user who is probably not a professional systems or security administrator. This paper examines what access control features are needed in a PDA and what assumptions are reasonable to make about its administration. It then presents an access control system to provide these features subject to the administrative constraints.
