Abstract

A distributed object-oriented system stresses moduality through narrow and rigidly defined interfaces to build low coupling, highly antonomous components. A security system for such systems must preserve the scalability, maintainability and extensibility of it. This paper presents a security system called Petrus, which provides strong authentication and data encyption to the Renaissance object environment. Petrus combines public-key and secret key cryptography to achieve acceptable performance. In addition, to minimize coupling, Petrus reduces functions of the central authorties and delegates authentication and data encryption to individual clients and servers. By hiding security functions in the Petrus Layers in proxies to remote objects, Petrus provides flexible mechanisms for applications that are mostly unaware of security to enforce constrains specified by their security policy, making it easy for the construction and maintenance of secure distributed systems.
