Abstract
A shared key and a private key unique to one or more resource sets are generated. Each of the resource sets identifies the resource. The shared key and the private key are transmitted to a security access point. The security access point controls access to the resource. A resource key is generated. The resource key is a result of a cryptographic function of the private key and a resource identifier. The resource key and the shared key are transmitted to one or more local security managers. Each of the local security managers is assigned to manage one of the resource sets. In accordance with one or more policies, the local security managers generate a credential using the resource key and the shared key. The credential is distributed to one or more authenticated clients. Further, the credential is used to grant the one or more authenticated clients access to the resource sets through the security access point.
