Abstract
The subject disclosure pertains to systems and methods that facilitate managing access control utilizing certificates. The systems and methods described herein are directed to mapping an access policy as expressed in an access control list to a set of certificates. The set of certificates can be used to grant access to resources in the manner described by the ACL. The certificates can be distributed to entities for use in obtaining access to resources. Entities can present certificates to resources as evidence of their right to access the resources. The access logic of the sequential ACL can be transformed or mapped to a set of order independent certificates. In particular, each entry, position of the entry in the list and any preceding entries can be analyzed. The analysis can be used to generate order independent certificates that provide access in accordance with the access policy communicated in the ACL.
