Embodiment Construction
[0055] A method for secure data transmission between wireless ad hoc networks according to the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments:
[0056] First of all, it should be explained that the precondition of the method for secure data transmission between ad hoc networks in the present invention is that the ad hoc network has been successfully established, and all nodes in the ad hoc network have realized interconnection.
[0057] Such as figure 1 As shown, there are five online nodes in the wireless ad hoc network. Assume that node A is the sending node and node D is the receiving node. Node A needs to send the collected data to node D. According to the network topology diagram of the wireless ad hoc network, it can be seen Out, the data passes through node B, node C, and finally reaches node D. Then the data may be lost due to signal interference or network congestion when it is transm...

The invention discloses a method for safely transmitting data between wireless ad hoc networks. The method comprises the following steps that: a node constructs a node public key table; a sending node sends a data message to a receiving node; the receiving node sends a response message to the sending node after receiving the data message and carrying out security check; the sending node sends a data confirmation message to the receiving node after receiving the response message and carrying out security check and data comparison; and the receiving node receives the data confirmation message and selects to reserve or discard the data according to the type of the data confirmation message. According to the method, on the basis of a network architecture of the wireless ad hoc network, a hash algorithm, a public key cryptographic algorithm and an encryption authentication technology are fused, and a brand-new data security transmission method is designed, so that security interaction of data between internal nodes of the wireless ad hoc network is realized. The method is wide in application range, easy to implement, safe and reliable, and can be used in some network environments with extremely high security requirements.
Description
technical field [0001] The invention relates to a method for secure data transmission between wireless ad hoc networks, in particular to the safe transmission of sensitive data between wireless ad hoc networks, and belongs to the technical field of combining wireless communication and cryptography. Background technique [0002] Wireless ad hoc network, also known as Mesh network, is a wireless communication system that supports multi-hop relays. Each node in the system can move freely. When the system topology changes, it can quickly reconfigure the route and form a new network topology, ensuring real-time The interconnection and intercommunication of all online nodes in the system, the wireless ad hoc network is especially suitable for applications such as on-site emergency command and fast team networking, and is currently widely used in public security, emergency and military industries. [0003] In view of the particularity of the application of the wireless ad hoc netwo...
