Abstract:
1. A method for controlling access to at least one resource, the method comprising the steps of: generating at least one shared key and at least one private key unique to one or more resource sets, wherein each of the one or more resource sets identify the at least one resource; transmitting the at least one shared key and the at least one private key to a security access point, wherein the security access point controls access to the at least one resource; generating at least one resource key, wherein the at least one resource key is a result of a cryptographic function of the at least one private key and at least one resource identifier; and transmitting the at least one resource key and the at least one shared key to one or more local security managers, each of the one or more local security managers being assigned to manage one of the one or more resource sets, wherein the one or more local security managers generate, in accordance with one or more policies, at least one credential using the at least one resource key and the at least one shared key, wherein the at least one credential is distributed to one or more authenticated clients, the at least one credential being used to grant the one or more authenticated clients access to the one or more resource sets through the security access point.
