Embodiment Construction

[0056] The technical solution of the present invention has been described in detail in the content of the present invention, and will not be repeated here. It is worth pointing out that in a specific implementation process, the size of the security parameter k can be appropriately changed according to different security requirements. The higher the security requirements, the security parameters should be appropriately increased. At the same time, the random number selected by each user must be safely saved during the session, and it must be deleted safely after the session ends.

Abstract

An Ad Hoc network is a multi-hop temporary autonomous system consisting of a group of mobile terminals with wireless transceiving devices. The Ad Hoc network has excellent properties that traditional networks do not have, and the excellent properties enable the Ad Hoc network to have wide application prospect in the fields of military communication, disaster relief, temporary communication and the like. Because the Ad Hoc network has dynamic property and each terminal has low transmitting power, small communication bandwidth, limited energy and the like, a key exchange protocol in the Ad Hoc network must have the properties of dynamics, as little communication amount and calculation amount as possible and the like. The key exchange protocol of the invention not only has dynamic property and certifiable security, but also has smaller communication amount and calculation amount compared with the conventional schemes, so the key exchange protocol has higher application value in the Ad Hoc network. The scheme also can be used in the traditional networks.

Description

technical field [0001] The invention belongs to the technical field of communication, and is used for exchanging keys within a dynamic group, especially having high application prospects in Ad Hoc networks. Background technique [0002] Ad Hoc network is also called multi-hop network, infrastructureless network, self organization network, self-healing network or peer-to-peer network. It is a logical The networking method, which emphasizes the dynamic establishment of a network that can be interconnected by mobile terminals within a certain range without relying on basic network facilities. The Ad Hoc network does not need the support of wired infrastructure equipment, and realizes communication through the free networking of mobile hosts. The emergence of Ad Hoc network has promoted the process of people's free communication in any environment, and it also provides an effective solution for military communication, disaster relief and temporary communication.
