Knowledge graphs utilize a combination of technologies such as entities, attributes, relationships, and semantic annotations to demonstrate indispensable functionality in standardization processes, and especially excel in achieving semantic connectivity. This paper systematically analyzes the role of knowledge graph in each level using the standards hierarchical model as a framework. In Level 1, knowledge graph supports information extraction and preliminary tagging;in Level 2, it realizes structured and semantic processing of documents;in Level 3, it facilitates complex relationship modeling and executive integration;and it lays the foundation for advanced intelligent applications, autonomous standards governance and dynamic automatic updating in Level 4 and 5. This paper provides an in-depth discussion of its future directions and possible challenges, including key topics such as optimizing the scalability of knowledge graphs and facilitating cross-domain knowledge fusion. It shows that knowledge graphs provide powerful technical support for standards digitization and offer new possibilities for realizing smart manufacturing and cross-domain collaboration.展开更多

This manuscript summarized the four generations for the development of RS including physical RS, paper atlas, substitute RS and electronic databases. The advantages and disadvantages of each generation were summarized. The concept of digital RS (DRS) was proposed based on this, and summed up the definition, advantages, and technical architecture of DRS. The 10 characteristics of five aspects of the DRS were discussed including digital, multi-dimension, big data, cloud computing, internet, internet of things, sharing, multi-terminal, intelligence, and compliance certification. Then, the necessity of its formation and application in the medicine holistic quality control of internet plus era was discussed in this manuscript.展开更多

Most order-specified multisignatures specified the orders as linear ones. In this paper, we proposed an order-specified multisignature scheme based on DSA secure against active insider attack. To our knowledge, it is the first order-specified multisignature scheme based on DSA signature scheme, in which signers can sign in flexible order represented by series-parallel graphs. In the multisignature scheme verification to both signers and signing order are available. The security of the scheme is proved by reduce to an identification scheme that is proved have some concrete security. The running time of verifying a signature is comparable to previous schemes while the running time of multisignature generation and the space needed is less than those schemes.展开更多

In this article, we analyze the complexity of the batch verifying schemes defined by Li, Hwang and Chen in 2010, and propose a new batch verifying multiple digital signature scheme, in two variants： one for RSA - by completing the Harn＇s schema with an identifying illegal signatures algorithm, and the other adapted for a modified Elliptic Curve Digital Siggnature Algorithm protocol.展开更多
