Problems solved by technology

Later, researchers gradually introduced this idea of ​​anonymous communication into wireless sensor networks, among which there is a type of false traffic technology that can be summarized as resisting traffic analysis, such as the sensor network layered anonymous communication protocol (HACP) proposed by A.Durresi, which In this method, in order to ensure the anonymity of the communication nodes, it is necessary to send false data packets to the communication nodes to hide the real data packets to achieve the purpose of anonymous communication, but this method brings huge communication energy consumption to the communication network and communication resource occupancy
Another type can be summarized as an anonymous communication mechanism based on forwarding, through the reconstruction of the routing path to achieve the purpose of anonymity of the sender and the anonymity of the receiver, such as the phantom routing protocol proposed by Ozturk and Kamat et al. Walking to a pseudo-source node in the network, and then routing the message from the pseudo-source node to the Sink node, this method uses flooding technology, making it difficult for the attacker to collect the location information of the information, but this method gives communication The network brings huge energy consumption and occupation of communication resources

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] An anonymous communication method of a wireless sensor network provided by the present invention, wherein the topology of the wireless sensor network is as follows figure 1 Specifically, it includes the following three aspects:

[0031] (1) Anonymous session key negotiation

[0032] 1) In the initial state of the network, the base station acts as the security management center of the wireless sensor network. The base station generates and assigns an identity ID to each node in the network as a unique identity mark. The generation rules are: Among them, n is the number of nodes in the network, and H() represents a strong cryptographic Hash function. The base station generates corresponding parameters according to each generated node ID where i=1, 2, . . . , n. s is a random number known only by the base station. The base stat...

Abstract

The invention relates to an anonymous communication method of a wireless sensor network, which belongs to the technical field of wireless communication. The method is designed by using bilinear pairing function, hash function and XOR operation. In the session key negotiation phase of the nodes, the nodes in the wireless sensor network calculate and generate the session key without exposing the real identity ID of each other. information, and only legal nodes can pass mutual authentication between nodes; after the secure communication link is established between wireless sensor network nodes, the source node and destination node in the network use their respective pseudonyms during data communication. The identity ID information replaces the real identity ID information for communication, and uses the session key to encrypt the message payload. This method can effectively guarantee the anonymity of the source node, destination node and communication relationship in the wireless sensor network, and can effectively resist the sensitive information in the wireless sensor network message analyzed by the attacker through flow analysis and other methods.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to an anonymous communication method of a wireless sensor network. Background technique [0002] Wireless sensor network is composed of many miniature sensor nodes, and it is a task-oriented wireless self-organizing network. These nodes are densely deployed in designated areas, and a multi-hop wireless network formed by self-organization is used to collect, sense and process environmental information and target data in the monitoring area, and transmit the collected and sensed information and data to the terminal Users or monitoring centers collaborate to complete assigned tasks. As one of the most influential technologies in the 21st century, wireless sensor networks have advantages that traditional information technology cannot match in many emerging fields. With the continuous development of information technology, wireless sensor networks will inevitably appear in ...
