ABSTRACT: With reference to a protection model featuring processes, objects and domains, we consider the salient aspects of the protection problem, domain representation and access right segregation in memory. We propose a solution based on protected references, each consisting of the identifier of an object and the specification of a collection of access rights for this object. The protection system associates an encryption key with each object and each domain. A protected reference for a given object is always part of a domain, and is stored in memory in the ciphertext form that results from application of a double encryption using both the object key and the domain key.
