Embodiment Construction

[0060] The specific design process of the media medium access control method based on secure multi-channel is as follows:

[0061] Step 1: Establish a certification center CA, and generate different group keys KG for different groups of wireless nodes.

[0062] Firstly, according to the needs of the network, a certification center CA is established, and the key distribution can be undertaken by the CA. It is assumed that each node of the network initialization node requests the group key KG from the CA after identity authentication.

[0063] Step 2: key distribution, distribute the key KG of the group according to the group to which the wireless node belongs.

[0064] The corresponding key KG is selected according to the group to which the node belongs. Assuming that the generated key can be safely transmitted to the wireless terminal node, the key can be distributed by using a secure key distribution protocol.

[0065] Step 3: The source node initiates a data transmission re...

Abstract

The invention relates to a safe multi-channel media access control method of a wireless self-organizing network, which is a safe communication mechanism for effectively improving network throughput in the wireless network. The method is mainly used for solving the safe transmission problem of the multi-channel media access control protocol, the safe multi-channel media access control communication method is designed and developed, and the method is characterized in that the method is expanded on the basis of the existing multi-channel media access control communication, the multi-channel media access control mechanism of dynamic channel allocation of a signal-interface multi-channel separation control channel which is currently extensively studied is utilized, and the lightweight fast encryption algorithm is introduced for protecting control packets. The computational burden of the verification process is further reduced through a blacklist mechanism for filtering source addresses.

Description

technical field [0001] The invention designs a security media medium access control method in wireless self-organizing network communication, which is used to solve the security communication problem in multi-channel media medium access control protocol under wireless network, and belongs to the field of wireless data network and wireless self-organizing network. Background technique [0002] A wireless ad hoc network is a wireless network without fixed infrastructure support, which has the characteristics of multi-hop, dynamic changes in topology and channel environment. It can be widely used in the fields of military, natural disaster rescue, scientific investigation and emergency communication. [0003] The medium access control (Medium Access Control) protocol in the wireless ad hoc network controls the access channel of the wireless terminal, and is located between the network interface layer of the network protocol software and the link layer. It plays an important ro...
