They first created an underlying certificateless signature (CLS) scheme, and then proposed a CLAS scheme from the underlying CLS scheme by adding an aggregation algorithm and a verification algorithm. In this paper, we point out that their CLS scheme is insecure because the Type I adversary can forge valid signatures. That is, the unforgeability is not actually captured by their CLS scheme. Finally, we map our cryptanalysis to the practical application. That is, in the practical application of HWMSNs, the attacker can launch real attack to their CLS scheme using our cryptanalysis to forge signatures. Therefore, Qiao et\u00a0al.\u2019s CLS scheme can be totally broken.<\/jats:p>","DOI":"10.1093\/comjnl\/bxae048","type":"journal-article","created":{"date-parts":[[2024,6,8]],"date-time":"2024-06-08T20:01:53Z","timestamp":1717876913000},"page":"2819-2822","source":"Crossref","is-referenced-by-count":3,"title":["On
