Trust management is a concept of automatic verification of access rights against distributed security policies. A policy is described by a set of credentials that define membership of roles and delegation of authority over a resource between the members of roles. Making an access control decision is equivalent to resolving a credential chain between the requester and the role, which members are...

The need to manage large information repositories in a secure, distributed environment increases with the growth of the Internet. To address this need, a system capable of managing the contents of an LDAP directory over the Web has been designed and developed. This system allows for the directory’s data to be divided into communities and supports the delegation of administrative authority over ...

The UniText tool is a concept in development that takes into account the distributed nature of documentation, which consists of multiple documents linked to several parts of the system described at different levels of abstraction, and produced by different people with different authority levels. UniText can manage the traceability of all the documentation units according to several criteria (au...

Security enforcement mechanisms for controlling the execution of untrusted component code have evolved away from the strict sandbox confinement toward more flexible code access security. Although the added flexibility has enabled richer functionality and support for more fine-grained policies, component-based security architectures such as Java and .NET still fail to provide several essential f...

This paper studies the optimal design of delegation rule in a three-tier principalintermediary-agent hierarchy. In this hierarchy, monetary transfer is not feasible, delegation is made sequentially, and all players are strategic. We characterize the optimal delegation mechanism. It is shown that the singleinterval delegation a la Holmstrom is optimal only when the intermediary is moderately bia...

Abstract Recently, in their 2019 paper, Poyago-Theotoky and Yong consider a managerial Cournot duopoly with pollution externalities emission taxes propose an explicit environmental incentive compensation contract. The authors compare several exogenous equilibria emerging the symmetric sub-games which owner offers either delegation contract or standard sales contract: abatement social welfare (r...

In this paper we explore the relationship between selforganization of multiagent systems and adjustable autonomy in intelligent agents. To discuss multiagent organizations, we introduce the Framework for selfOrganization and Robustness in Multiagent systems (FORM). This framework uses delegation as the central concept to define organizational relationships in taskassignment multiagent systems. ...

The main aim of access control models is to provide means to simplify the management of the security policy, which is a fastidious and error-prone task. Supporting delegation is considered as an important mean to decentralize the administration and therefore to allow security policy to be more flexible and easier to manipulate. Our main contribution is the proposition of a unified model to the ...
