“…Whereas, Quan et al [1] have presented the taxonomy of delegation, where it was elaborated that who can initiate delegation, how delegation is processed, where delegation is honored, etc. However, their taxonomy has been presented in implementation perspective only, while we will provide detailed taxonomy of delegation that covers some additional delegation aspects (such as delegation forms, scenarios).…”

Protection of shared data from unauthorized users is the most challenging problem of cyber security for which different access control models have been introduced. However, to provide flexibility in access control models, access rights are delegated within a single security domain or across multiple security domains for different collaborative activities. To the best of our knowledge, there is no published standard for delegation models. Therefore, organizations are unable to evaluate existing delegation models when they have to choose appropriate solution that best satisfies their business requirements. In this paper, we have done literature survey and presented the taxonomy of delegation model, which classifies and elaborates the different features, concepts and scenarios of delegation. Presented taxonomy has been used, in this paper, as an assessment criterion for the evaluation of existing delegation models. Finally, we have compared these models against our taxonomy. Our presented taxonomy is very useful to understand the basic delegation concepts and may be first step toward standardization process.

“…Delegation is defined as the process whereby a user without any administrative prerogatives obtains the ability to grant some authorizations [1]. It can be considered as a potential approach in addressing the problem of providing dynamic access control decisions in activities with a high level of collaboration [2]. Hence, delegation is used in order to facilitate responsibilities interaction between subjects.…”

Security Policies (SP) constitute the core of communication networks protection infrastructures. It offers a set of rules allowing differentiating between legitimate actions and prohibited ones and consequently, associates each entity in the network with a set of permissions and privileges. Moreover, in today's technological society and to allow applications perpetuity, communication networks must support the collaboration between entities to face up any unavailability or flinching. This collaboration must be governed by security mechanisms according to the established permissions and privileges. Delegation is a common practice that is used to simplify the sharing of responsibilities and privileges. The delegation process in a SP environment can be implanted through the use of adequate formalisms and modeling. The main contribution of this paper is then, the proposition of a generic and formal modeling of delegation process. This modeling is based on three steps composing the delegation life cycle: negotiation used for delegation initiation, verification of the SP respect while delegating and revocation of an established delegation. Hence, we propose to deal with each step according to the main delegation characteristics and extend them by some new specificities

This paper extends digital credentials, a cryptographic scheme that provides provably secure, private, attribute certificates. We give a method for the delegation of these credentials, which allows the delegator to reveal a subset of his/her credentials to a delegatee, who in turn can control revelation of this subset to a verifier. Our method also supports blinded showing of credentials to a specified verifier in order to hide the credentials from the delegatee, when desired. Privacy is preserved in all cases under a strong attack model that includes collusion between an attacker (Malice) and the Certification Authority that issued the credentials.
