Abstract :
Delegation is commonly used in organizations to transfer some permission by one user to another user. However, most existing delegation schemes do not support supervision, which allows the delegators to retain control over how the delegated permission can be exercised. In this paper, we describe how to support efficient authorization in delegation with supervision using proxy signature techniques
