| 摘 要： | A complex threshold key management framework has been proposed, which can address the challenges posed by the unique nature of Ad hoe network. Depending on the cooperation of the controller and participation nodes, this scheme should be efficient in the operation environmental alteration and tolerant faults of node, which take the advantages of the benefits of both key management approaches and alleviate their limitations. For the cooperation of the controller and participation nodes, a (t,n) threshold Elliptic curve sign-eneryption scheme with the specified receiver a/so has been proposed. Using this threshold signencryption scheme, the key management distributes the trust between a controller and a set of participation nodes.

| Abstract: | A complex threshold key management framework has been proposed, which can address the challenges posed by the unique nature of Ad hoc network. Depending on the cooperation of the controller and participation nodes, this scheme should be efficient in the operation environmental alteration and tolerant faults of node, which take the advantages of the benefits of both key management approaches and alleviate their limitations. For the cooperation of the controller and participation nodes, a (t, n) threshold Elliptic curve sign-encryption scheme with the specified receiver also has been proposed. Using this threshold sign-encryption scheme, the key management distributes the trust between a controller and a set of participation nodes. |
