We describe the design and implementation of a trust-management system Soutei, a dialect of Binder, for access control in distributed systems. Soutei policies and credentials are w...
—We characterize the stability region of wireless, single-hop networks with time-varying imperfect channels. We define a joint scheduling and transmission rate control policy th...
Existing software infrastructures and middleware provide uniform security services across heterogeneous information networks. However, few, if any, tools exist that support access...
