  • Publication number: 20140207909
    Abstract: A method and system for transferring licenses between electronic devices supporting licensable features. Specifically, in a method a request is generated for transferring a license between first and second electronic devices. The request includes first information unique to the first electronic device, second information unique to the second electronic device. The request is sent to a license distributor to generates a master key. The master key includes a removal key including the first information and an add key including the second information. The removal key is used to remove the license from the first electronic device when the first information matches official versions of the first information. The add key is revealed from the master key when the license is successfully removed. The add key is used to add the license to the second electronic device when the second information matches official versions of the second information.

  • Patent number: 8126814
    Abstract: A method and system for installing software and hardware licenses on electronic devices supporting licensable features. Specifically, a method is disclosed for installing licenses in a node based licensing scheme. The electronic device defining the node receives an input containing an authorization key. The authorization comprises a license for a service feature, a node identifier, a software version, and a sequence number. Information in the authorization key is used to install the license on the electronic device. The node identifier is compared to an official node identifier stored at the electronic device. The sequence number is compared to an official sequence number stored at the electronic device. The license is installed into a pool of licenses available to the electronic device when the node identifier matches the official node identifier and the sequence number matches the official sequence number. The sequence number ensures that the authorization key at most can only be used once.

  • Patent number: 7586855
    Abstract: A system and method to detect non-native storage components to manage configuration in a communications network are disclosed. A stored key set is retrieved from each storage component of a network switch in a communications network, the stored key set identifying each storage component in relation to the switch. The stored key set of each storage component is validated. Finally, a new key set is generated for each storage component if the stored key set is an invalid key set.
