Embodiment Construction

[0031] The embodiments and effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] The traditional Internet of Things system can effectively ensure the safe collection and on-chain process of off-chain data, while the blockchain system can ensure the immutability and traceability of data after on-chain. The integration of blockchain and the Internet of Things can effectively improve the security of equipment and data, ensure the credibility of the process, and realize the coordinated operation of multiple entities. However, due to the lack of compatibility between the current IoT devices and the blockchain, there are still many security loopholes in the blockchain + IoT system. Therefore, realizing the encryption technology adaptation of the Internet of Things and the blockchain system is one of the problems that needs to be solved urgently.

Abstract

The invention belongs to the technical field of Internet of Things information security, and in particular relates to a lightweight data encryption method for a block chain-oriented Internet of Things chip. The details are as follows: IoT terminals use true random numbers to generate public and private keys, obtain digital certificates through certificate authorities, and use ECDH key exchange algorithms to exchange symmetric keys with blockchain gateways. The blockchain gateway receives the digital certificate and public key from the IoT terminal, and submits a transaction request to the alliance blockchain. After the alliance blockchain is endorsed and sorted, the list of trusted devices will be uploaded to the chain. When the data user requests to use the data, the IoT terminal will send the ciphertext data to the blockchain gateway with an ECDSA digital signature, and the blockchain gateway will forward it to the data user. The data user queries the list of trusted devices on the chain, and uses the trusted public key to verify the digital signature to ensure the authenticity of the data source. The invention can realize credible data source, safe data transmission and credible sharing on the data chain.

Description

technical field [0001] The invention belongs to the technical field of Internet of Things information security, and particularly relates to a blockchain-oriented lightweight data encryption method for Internet of Things chips. Background technique [0002] Encryption technology focuses on information confidentiality, and also involves information integrity verification, non-repudiation of information release, and all information security issues arising from internal and external attacks in distributed computing. At present, there are many branches of encryption technology such as symmetric encryption technology, asymmetric encryption technology and irreversible encryption technology, which are the theoretical basis and core technology of information security. [0003] The Internet of Things is a ubiquitous connection between things and people, and things and people through network access. It is the information carrier of the Internet, traditional telecommunication networks, ...
