Soutei, a logic-based trust-management system Andrew Pimlott and Oleg Kiselyov Soutei is a trust-management system, a dialect of Binder, for access control in distributed systems. Soutei policies and credentials are written in a declarative logic-based security language and thus constitute distributed logic programs. Soutei policies are modular, concise, and readable. They support policy verification, and, despite the simplicity of the language, express role- and attribute-based access control lists, and conditional delegation.
