technical field [0001] The invention belongs to the technical field of network security communication, and in particular relates to a lightweight authentication method, system and intelligent terminal based on the Ethereum IoT entity. Background technique [0002] At present, the closest existing technology: With the rapid development of the Internet of Things, the number of Internet of Things devices has increased dramatically, from smart locks to smart vehicles, from smart wearable devices to smart homes, the Internet of Things involves all aspects of people's lives. People use these IoT devices to generate, process and exchange a large amount of sensitive and private information, which has also induced many network attacks. Therefore, solving terminal authentication and access control is very important to the security and privacy issues in the Internet of Things. However, due to the limited resources, heterogeneity of device resources, strong dispersion and large scale o...

AI Technical Summary

Problems solved by technology

[0003] So far, many blockchain-based IoT security and trust management architectures have been proposed. However, most of the solutions do not fully consider the limited resources, strong dispersion, and large-scale characteristics of IoT devices. When the technology implements IoT authentication, the structure is complex, the authentication process is cumbersome, and the transaction confirmation time is prolonged; there is no detailed proposal for an IoT entity authentication protocol based on Ethereum

[0004] To sum up, the problems existing in the existing technology are: the existing blockchain-based architecture for IoT security and trust management does not fully consider the limitations of IoT device resources and the characteristics of application scenarios, resulting in computationally intensive encryption. The operation is difficult to realize, and the authentication scheme is not scalable and difficult to upgrade, making it difficult to implement the POW mechanism

The system architecture is complex, and the authentication protocol process is cumbersome, resulting in too long blockchain node consensus time and request response delay, which is not conducive to wide application in the delay-sensitive Internet environment

[0005] Difficulty in solving the above technical problems: It is not easy to adopt blockchain technology in the Internet of Things environment, and it faces several major challenges. For example, IoT entities generally have problems such as low computing power and short battery life. It is necessary to solve the high resources of POW Requirements; the authentication protocol is complicated, the consensus confirmation transaction takes a long time, and there is a performance bottleneck in the delay-sensitive Internet of Things; low scalability caused by broadcasting transactions to the entire network
