Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings and technical solutions.

[0026]Aiming at how to ensure data security in the Internet of Things and control of sensor data transmission while adapting to the data processing capabilities of sensor nodes. The identity information of the node is the special identification of the node, which solves the overhead problem of certificate storage and management. Considering the node processing capability of WSNs, the present invention reduces the calculation amount of edge nodes, splits the private key at the same time, and stores the private value at the node, so as to reduce the amount of data storage at the node and reduce the complexity of adding and deleting nodes . The mass data obtained by the sensor is real-time, and the environmental information is collected periodically at a certain frequency, and the data is continuously updated...

Abstract

The invention provides an authorized digital signature method for sensor network communication in a secure Internet of Things, belongs to the field of communication technology, and is used for authorizing and encrypting a sensor communication process in a secure Internet. The specific method is to first adopt the method of authorized signature, control the data sending process, reasonably schedule the signature data, and restrict the signature conditions. The scheme is based on the bilinear pairing problem, which guarantees the security and signature efficiency of the scheme. At the same time, private key splitting makes this scheme more suitable for the limitations of node computing power, storage space and energy storage in the Internet of Things. In addition, this solution uses timestamps, which not only solves the replay attack, but also facilitates conditional screening after data transmission to determine the correctness of the data.

Description

technical field [0001] The invention belongs to the field of communication technology, and relates to an authorized digital signature scheme for sensor network communication in the secure Internet of Things, which ensures data security in the Internet of Things and control of sensor data transmission under the data processing capability of sensor nodes, and improves Security of IoT data communication. Background technique [0002] With the rapid development of sensor network communication, the concept of Internet of Things (IOT) is always in a dynamic and expanding process. The Internet of Things has become the third wave of the development of the world's information industry after computers and the Internet. With the development of the Internet of Things, human travel, work, life, and even the interaction between government and enterprises are increasingly applied to sensor networks and IOT. However, due to the characteristics of IoT data processing and the requirements f...
