Secure Social Internet of Things Based on Post-Quantum Blockchain

With the advancement of the application of Internet of Things (IoTs), the IoT technology is combining with the social network, forming a new network with private object information as the media and social entertainment as the purpose. Social Internet of things (SIoTs) is a new application of IoT technology in social network. The current SIoT systems are centralized and the user's security and privacy is not properly protected. In order to address the challenges in SIoTs, we propose a privacy protection system for the users. First, we propose a post-quantum ring signature. Second, we propose a blockchain system based on the ring signature. Compared with the traditional SIoTs, our system is based on post-quantum techniques, which is secure against both traditional computers and quantum computers. The results of the blockchain system show that it is very suitable for SIoTs.

Automated summary

This article introduces the concept of Social Internet of Things (SIoTs) which combines IoT technology and social network, highlighting the issues with current centralized SIoT systems. The proposed privacy protection system utilizes post-quantum ring signature and blockchain technology, providing enhanced security against both traditional computers and quantum computers. The results suggest that the blockchain system is highly suitable for SIoTs.
