摘要
In order the 1st computing device, regarding the 1st user equipment to run the key management function to be constituted, in order furthermore the 2nd computing device, regarding the 2nd user equipment to run the key management function be constituted, the 1st user equipment, the 2nd user equipment communication it is started in the partner to request the fact that, the 1st computing device or the 2nd computing device, the 1st computing device and exists beforehand between the 2nd computing device not to have the security association which, furthermore the 3rd computing device, key managementIn order to run function, as it is constituted, the 3rd computing device, the 1st computing device and responding to step and this request which receive empty request either of the 2nd computing device the communication system which possesses with the security association to which the 1st computing device exists beforehand and the security association which the 2nd computing device exists beforehand in, after that, the 1st computing device and the 2nd computing device, the 1st user equipment and makes the establishment of the security association between the 2nd user equipment smoothIn order for it to be possible, the manner which has with the 1st computing device and the step which makes the establishment of the security association between the 2nd computing device smooth is run. 1st the computing device, 2nd the computing device, and 3rd the computing device key management hierarchy has one part at least, 1st the computing device and 2nd as for the computing device, is a level where this hierarchy is lower, furthermore 3rd as for the computing device, is a level where this hierarchy is higher.
