Some improved technologies are known to speed up processing capacity by shrinking the consensus group, increasing the block capacity and\/or shortening the block interval. Even these solutions are met with major problems such as storage limitations and weak security. To face the realistic application scenarios for blockchain technology in the mobile realm, we propose a new public blockchain designed based on sharding, aggregate signature and cryptographic sortition which we call SAC. In SAC, the transaction rate increases with the number of shards while the length of the consensus signature is a constant. Meanwhile, in SAC, the assignment of consensus representatives is controlled by a verifiable random function, which can effectively solve the problem of centralized consensus. In addition, this paper analyzes the performance of SAC to give adequate comparison with other sharding technologies while also giving a rational security analysis. Our experimental results clearly show the potential applicability of this novel blockchain protocol to in mobile computation.<\/jats:p>","DOI":"10.3233\/jhs-210653","type":"journal-article","created":{"date-parts":[[2021,3,26]],"date-time":"2021-03-26T17:46:12Z","timestamp":1616780772000},"page":"83-99","source":"Crossref","is-referenced-by-count":1,"title":["New public blockchain protocol based on sharding and aggregate signatures"],"prefix":"10.1177","volume":"27","author":[{"given":"Jinhua","family":"Fu","sequence":"first","affiliation":[{"name":"College of Software Engineering, Zhengzhou University of Light Industry, Zhengzhou 450002, China"},{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"}]},{"given":"Wenhui","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Software Engineering, Zhengzhou University of Light Industry, Zhengzhou 450002, China"}]},{"given":"Mixue","family":"Xu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"}]},{"given":"Xueming","family":"Si","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"},{"name":"School of Computer science, Fudan University, Shanghai 201203, China"}]},{"given":"Chao","family":"Yuan","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"}]},{"given":"Yongzhong","family":"Huang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Mathematical Engineering and Advanced Computing, Zhengzhou 450001, China"},{"name":"School of Computer Science and Information Security, Guilin University of Electronic Technology, Guilin 541004, China"}]}],"member":"179","reference":[{"key":"10.3233\/JHS-210653_ref5","doi-asserted-by":"crossref","unstructured":"B.\u00a0Dan et al., Aggregate and verifiably encrypted signatures from bilinear maps, in: Lecture Notes in Computer Science, Vol.\u00a03536, 2003, pp.\u00a0416\u2013432.","DOI":"10.1007\/3-540-39200-9_26"},{"key":"10.3233\/JHS-210653_ref6","doi-asserted-by":"publisher","DOI":"10.1109\/P2P.2013.6688704"},{"key":"10.3233\/JHS-210653_ref10","doi-asserted-by":"crossref","unstructured":"O.\u00a0Hueber, The blockchain and the sidechain innovations for the electronic commerce beyond the Bitcoin\u2019s framework, International Journal of Transitions & Innovation Systems 6(1) (2018).","DOI":"10.1504\/IJTIS.2018.090770"},{"key":"10.3233\/JHS-210653_ref13","doi-asserted-by":"publisher","DOI":"10.1109\/SP.2018.000-5"},{"key":"10.3233\/JHS-210653_ref17","doi-asserted-by":"crossref","unstructured":"H.\u00a0Morita, J.C.N.\u00a0Schuldt, T.\u00a0Matsuda et al., On the security of the Schnorr signature scheme and DSA against related-key attack, in: Information Security and Cryptology, Springer International Publishing, 2015, pp.\u00a020\u201335.","DOI":"10.1007\/978-3-319-30840-1_2"},{"key":"10.3233\/JHS-210653_ref19","unstructured":"R.M.\u00a0Parizi, A.\u00a0Dehghantanha, K.K.R.\u00a0Choo and A.\u00a0Singh, Empirical vulnerability analysis of automated smart contracts security testing on blockchains, in: Proceedings of the 28th Annual International Conference on Computer Science and Software Engineering, IBM Corp., 2018, October, pp.\u00a0103\u2013113."},{"key":"10.3233\/JHS-210653_ref23","doi-asserted-by":"publisher","DOI":"10.1109\/SP.2017.45"},{"key":"10.3233\/JHS-210653_ref26","first-page":"1","article-title":"Research on a new signature scheme on blockchain","volume":"2","author":"Yuan","year":"2017","journal-title":"Security and Communication Networks"}],"container-title":["Journal of High Speed Networks"],"original-title":[],"link":[{"URL":"https:\/\/content.iospress.com\/download?id=10.3233\/JHS-210653","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T08:38:14Z","timestamp":1741682294000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/full\/10.3233\/JHS-210653"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3,29]]},"references-count":8,"journal-issue":{"issue":"1"},"URL":"https:\/\/doi.org\/10.3233\/jhs-210653","relation":{},"ISSN":["1875-8940","0926-6801"],"issn-type":[{"type":"electronic","value":"1875-8940"},{"type":"print","value":"0926-6801"}],"subject":[],"published":{"date-parts":[[2021,3,29]]}}}
