A certificateless signature method and system suitable for industrial internet data perception

Abstract

The certificateless signature method suitable for industrial internet data perception provided by the embodiment of the invention comprises the following steps: the key generation center generates a public parameter and a main key by adopting a predetermined algorithm and broadcasts the public parameters to a first user node in the Internet of Things, the first user node generates a first privatekey and a first public key of the first user node according to the identification information and the public parameters of the node, and receives a first public key sent by the first user node and identification information of first user node equipment, and the first public key and the identification information of the first user node equipment generate a second public key and a second private keyfor the first user node, and send the second public key and the second private key to the first user node, so that the first user node generates a complete public key and a complete private key. According to the method, the node generates the complete key according to the two parts of keys, and a Hash function mapped to the point based on an existing certificateless signature scheme is not needed.

Description

technical field [0001] The present invention relates to the Internet of Things technology, and more specifically, to a certificateless signature method and system suitable for industrial Internet data perception. Background technique [0002] The achievements of the rapid development of the Internet of Things and cloud computing play an important role in building an intelligent world. In particular, the combination of cloud computing and industrial Internet of Things is considered to be a good solution to change the operation of existing industrial systems, which involve industrial production, logistics, storage and sales. Cloud-assisted IIoT enables various industries to gain competitive advantages, however several fundamental but challenging issues remain, including data authenticity, untrusted third parties, system robustness and efficiency. Since the essential information extracted from IIoT data often plays an important role in improving business operations, if data co...
