Key generation method, system and equipment in Internet of things

Abstract

The embodiment of the invention discloses a key generation method, a key generation system and key generation equipment in Internet of things, relates to the field of network security and is used for solving the problem of realizing the key distribution and management on the premise of data encryption in the Internet of things. According to the method, the system and the equipment, a terminal obtains a basic key according to a generated first random number, identification information of a communication intelligent card in the terminal and a hashing algorithm, a server end obtains a basic key according to the first random number sent by the terminal, the identification information of the communication intelligent card in the terminal and the hashing algorithm, the terminal and the server end locally generate the basic keys, the key distribution and management operation is avoided, and the realization flow process of the data encryption is simplified.

Description

Technical field [0001] The present invention relates to the field of network security, in particular to a method, system and equipment for generating a key in the Internet of Things. Background technique [0002] The Internet of Things (IOT) has implanted the concept of "smart" in infrastructure and ubiquitous information sharing, interaction and integrated services, setting off another technological revolution following the Internet wave. [0003] The Internet of Things is a relatively new network. Its purpose is to connect all the things in the world to the network. Therefore, it uses a multi-network form network with wireless sensor networks as the main and various other networks as a supplement. Due to its special application requirements, it has many different characteristics from traditional networks. [0004] One of the more prominent problems in the Internet of Things is the limited node resources, which mainly refers to the limited computing capacity, storage capacity, comm...

Problems solved by technology

[0009] At present, PKI technology is used in the Internet of Things to encrypt communication data. In PKI technology, the public key and private key need to be distributed to both communication parties, and key management is required. The implementation process is cumbersome.
