Collaboration among independent administrative domains would require: i) confidentiality, integrity, non-repudiation of communication between the domains; ii) minimum and reversible modifications to the intra-domain precollaboration setup; iii) maintain functional autonomy while collaborating; and, iv) ability to quickly transform frompost-collaboration to pre-collaboration stage. In this paper, we put forward our mechanism that satisfies above requirements while staying within industry standards so that the mechanism becomes practical and deployable. Our approach is based on X.509 certificate extension. We have designed a non-critical extension capturing users' rights in such a unique way that the need for collaboration or the post-collaboration stage does not require update of the certificate. Thus, greatly reducing the revocation costs and size of CRLs. Furthermore, rights amplification and degradation of users from collaborating domains into host domain can be easily performed. Thus, providing functional autonomy to collaborators. Initiation of collaboration among two domains require issuance of one certificate from each domain and revocation of these certificates ends the collaboration - ease of manageability.

Abstract

Collaboration among independent administrative domains would require: i) confidentiality, integrity, non-repudiation of communication between the domains; ii) minimum and reversible modifications to the intra-domain precollaboration setup; iii) maintain functional autonomy while collaborating; and, iv) ability to quickly transform frompost-collaboration to pre-collaboration stage. In this paper, we put forward our mechanism that satisfies above requirements while staying within industry standards so that the mechanism becomes practical and deployable. Our approach is based on X.509 certificate extension. We have designed a non-critical extension capturing users' rights in such a unique way that the need for collaboration or the post-collaboration stage does not require update of the certificate. Thus, greatly reducing the revocation costs and size of CRLs. Furthermore, rights amplification and degradation of users from collaborating domains into host domain can be easily performed. Thus, providing functional autonomy to collaborators. Initiation of collaboration among two domains require issuance of one certificate from each domain and revocation of these certificates ends the collaboration - ease of manageability.
