We present a framework to support consumable credentials in a logic-based distributed authorization system. Such credentials convey use-limited authority (e.g., to open a door once) or authority to utilize resources that are themselves limited (e.g., to spend money).We design a framework based on linear logic to enforce the consumption of credentials in a distributed system, and to protect credentials from nonproductive consumption as might result from misbehavior or failure. Finally, we give
