This feature offers an innovative way for conventional wireless customers to access enhanced internet services by using SIN. However, SIN\u2019s characteristics, such as naked links and maximum signal latency, make it difficult to design efficient security and routing protocols, etc. Similarly, existing SIN authentication techniques can\u2019t satisfy all of the essentials for secure communication, such as privacy leaks or rising authentication latency. The article aims to develop a novel blockchain-based access authentication mechanism for SIN. The proposed scheme uses a blockchain application, which has offered anonymity to mobile users while considering the satellites\u2019 limited processing capacity. The proposed scheme uses a blockchain application, which offers anonymity to mobile users while considering the satellites\u2019 limited processing capacity. The SIN gains the likelihood of far greater computational capacity devices as technology evolves. Since authenticating in SIN, the technique comprises three entities: low Earth orbit, mobile user, and network control centre. The proposed mutual authentication mechanism avoids the requirement of a ground station, resulting in less latency and overhead during mobile user authentication. Finally, the new blockchain-based authentication approach is being evaluated with AVISPA, a formal security tool. The simulation and performance study results illustrate that the proposed technique delivers efficient security characteristics such as low authentication latency, minimal signal overhead and less computational cost with group authentication.<\/jats:p>","DOI":"10.1371\/journal.pone.0291236","type":"journal-article","created":{"date-parts":[[2024,3,7]],"date-time":"2024-03-07T13:53:26Z","timestamp":1709819606000},"page":"e0291236","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":5,"title":["Access
