Embodiment Construction
[0057] Such as Figure 1-10 As shown in one of the above, the present invention discloses a wireless ad hoc network encryption communication method, and a new network terminal can only be connected to the wireless ad hoc network after passing the access authentication. Before each call, the calling terminal searches for the best path of the called terminal according to the routing protocol of the ad hoc network, and then initiates a call request to the called terminal. After the called terminal accepts the call request, it sends the public key to the calling terminal. The calling terminal randomly generates a communication key for each call, and uses the received public key and asymmetric encryption technology to encrypt the communication key. The encrypted communication key is sent from the calling terminal to the called terminal through the wireless ad hoc network. The called terminal uses the private key to decrypt the communication key. The calling terminal and the call...

The invention discloses a wireless ad hoc network encryption communication method and terminals thereof. Each terminal can join in a wireless ad hoc network only after passing access authentication, and illegal terminals are prevented from invading the network. Different communication keys are adopted to encrypt communication data in the call connections, so that eavesdropping of other users in the network is prevented. The communication key is encrypted through an asymmetric encryption technology and then is distributed in the ad hoc network, so that an attacker can be effectively prevented from cracking and stealing the communication key. The advantages of the two encryption technologies of asymmetric encryption and symmetric encryption are comprehensively adopted, the asymmetric encryption technology is used for safely distributing the communication secret key in the wireless network, and the symmetric encryption technology is used for achieving rapid encryption and decryption of communication data. According to the invention, the original advantages of the wireless ad hoc network can be maintained, the network security can be significantly enhanced, and the confidentiality andreliability of the whole communication system are improved.
Description
technical field [0001] The invention relates to the field of ad hoc networks, in particular to a wireless ad hoc network encryption communication method and a terminal thereof. Background technique [0002] Compared with ordinary mobile communication systems, wireless ad hoc network communication systems have the advantages of flexible networking, strong self-adaptation, multi-hop relay, self-healing, etc., without the need to deploy mobile base stations, backhaul networks, core networks and other construction cycles in advance Longer communication facilities can carry out mobile communication services. However, the convenience of the wireless ad hoc network also brings the vulnerability of the network, which is vulnerable to attack and eavesdropping. Contents of the invention [0003] The purpose of the present invention is to provide a wireless ad hoc network encryption communication method and its terminal, so that the wireless ad hoc network can not only maintain the ...
