In a hybrid network system which combines a wired network adopting PKI authentication and a wireless network adopting IBE authentication,it is difficult to authenticate other nodes in view of the different security polices and cryptosystemTo solve this problem,a cross-domain authentication scheme based on zero knowledge proof is proposedAn agency node is settled between the two heterogeneous trustworthy domains to certificate nodes'commitments in the zero knowledge proofThen a authentication protocol between heterogeneous trustworthy domains is designed to realize the authentication between nodes in different domains,and the correctness,security and efficiency of the protocol are analyzedThe results show that the proposed protocol is feasible and effective

Cross-domain Authentication Scheme Based on Zero Knowledge Proof

This work studies ways of Healthy City Construction (HCC) and Urban Governance Optimization (UGO) during the COVID-19 pandemic. The specific urban community space planning structure is proposed following a literature review on the healthy city’s theoretical basis and historical development. Then, the proposed HCC-oriented community space structure is tested by surveying residents’ physical and mental health and infectious risk using a questionnaire survey and Particle Swarm Optimization (PSO). Specifically, the particle fitness is calculated according to the original data conditions, and the community space with the highest fitness is determined. Based on the calculation, the community space’s neighbors are investigated from different aspects through a questionnaire survey on patients’ daily activities and community health security coverage. The results showed that: (1) The score of daily activities of community patients with respiratory diseases was 2312 before the implementation of the proposed community structure and 2715 after the implementation. Therefore, the service quality of residents increases after implementation. (2) The proposed HCC-oriented community space structure improves the physical self-control ability of chronic patients and helps them reduce their pain. This work aims to create a people-oriented healthy city community space, improve the city’s “immune system,” and regenerate the energy and environmental sustainability of the urban living environment.

Aiming at improving the enterprise performance and venture capital management, the edge computing is combined with blockchain technology in the construction of the supply chains so as to improve the stability and security of raw material supply chains of venture capital enterprises. Firstly, the relationships among venture capital, enterprise performance, and supply chain integration are analyzed, and the positive impacts of optimization and innovation of supply chain technology and venture capital on enterprise performance improvement are discussed. Secondly, the edge computing and blockchain technology are adopted to optimize the supply chain, and a protocol model is established to improve the security of supply chain information transmission. In addition, the supply chain Internet of Things (IoT) system is designed in layers based on blockchain and edge computing technology. Finally, the designed protocol model is applied to the supply chain and the supplier performance is evaluated by using the fuzzy analytic hierarchy process (FAHP). The results show that the gas value of the designed protocol model is stable at 104,000∼116,000 in blockchain transactions, and the execution time of a single blockchain transaction fluctuates between 4,300 and 6,100 ms. Therefore, the designed protocol model can effectively ensure the security of supply chain data during the transmission. The evaluation results of supplier performance suggest that the cooperative relationship between venture capital enterprises and suppliers is affected by many factors. Optimizing the supply chain structure and production activities can improve the performance of suppliers and venture capital enterprises. This work provides a reference for analyzing the performance of blockchain technology on venture capital enterprises and suppliers.

With the development of mobile communication, users put forward a higher security requirement in the process of intelligent mobile terminal to access different applications. A cross-domain authentication mechanism in the mobile Internet environment has been designed in this paper, which is B/S pattern. Firstly, the trust relationship between the Single Sign-on servers has been established by using SAML, then the design frame is Single Sign-on, as well as using HTTPS and ECC to encrypt data and the data transmissions. The user only needs to authenticate identity successfully in one trusted domain, then he can visit other trusted domains easily and does not need to authenticate identity again under the context that without exit. It is shown that a cross-domain authentication mechanism in the mobile Internet environment has been designed which raises the reliability of mobile terminal. This article uses identity-based encryption to calculate the public key and private key. Finally the paper verifies the proposed mechanism. Experiments show that this mechanism is convenient for the user's authentication, meanwhile it ensures the security and scalability of the system. It is proved that the cross-domain authentication mechanism has some reference meanings in the future research in this field.
