A secure and verifiable method for continuous data collection in sensor networks

Abstract

The invention discloses a security verifiable continuous data collection method in a sensor network. Sensing data in a period is reconstructed through time correlation; the reconstructed data is encrypted and then is sent to father nodes; and the data communication traffic can be effectively reduced under the condition of ensuring the security of the data. Moreover, the nodes generate fingerprints of the sensing data, so a sink can verify the collected sensing data; and the digits of the fingerprints are far shorter than the digits of the sensing data and the fingerprints and the sensing data can be fused, so the communication cost of the fingerprints is relatively low.

Description

technical field [0001] The invention relates to the technical field of wireless sensor network security, in particular to a safe and verifiable continuous data collection method in a sensor network. Background technique [0002] Wireless sensor networks are composed of a large number of sensor nodes deployed in the field, and have a wide range of applications in environmental monitoring, event monitoring, and medical and health fields. In many application scenarios, nodes need to periodically report sensing data to sink nodes. Since sensor node energy, computing and other resources are limited and cannot be maintained, saving energy and prolonging the service life of the network are important challenges for wireless sensor networks. . At the same time, the self-organizing network of multi-hop and wireless communication in wireless sensor networks makes wireless sensor networks face serious privacy leakage problems. Privacy protection is one of the important factors affectin...

AI Technical Summary

Problems solved by technology

Although the confidentiality and authenticity of the sensing data can be guaranteed through encryption and decryption technology, it is difficult to monitor the captured sensor nodes for attacks such as discarding or repeated transmission, so the Sink node needs to be able to verify the integrity of the collected data. necessary

The existing research on safe and verifiable data collection methods is basically blank. Therefore, targeted research on safe and verifiable data collection methods in wireless sensor networks is needed.
