Access control : Policies, models, and mechanisms
TL;DR: In this article, the basic concepts behind access control design and enforcement are investigated, and different security requirements that may need to be taken into consideration, and several access control policies and models formalizing them are discussed.
Journal ArticleDOI
A fine-grained access control system for XML documents
TL;DR: This work presents an access control model to protect information distributed on the Web that, by exploiting XML's own capabilities, allows the definition and enforcement of access restrictions directly on the structure and content of the documents.
Proceedings Article
Over-encryption: management of access control evolution on outsourced data
Sabrina De Capitani di Vimercati,Sara Foresti,Sushil Jajodia,Stefano Paraboschi,Pierangela Samarati +4 more
TL;DR: A novel solution to the enforcement of access control and the management of its evolution is presented, based on the application of selective encryption as a means to enforce authorizations.
Proceedings ArticleDOI
Choosing reputable servents in a P2P network
Fabrizio Cornelli,Ernesto Damiani,Sabrina De Capitani di Vimercati,Stefano Paraboschi,Pierangela Samarati +4 more
TL;DR: An approach to P2P security where servents can keep track, and share with others, information about the reputation of their peers is proposed, based on a distributed polling algorithm by which resource requestors can assess the reliability of perspective providers before initiating the download.
Journal ArticleDOI
An algebra for composing access control policies
TL;DR: An algebra of security policies together with its formal semantics is proposed and how to formulate complex policies in the algebra is illustrated, which provides the basis for the implementation of the algebra.
