VisTAS: blockchain-based visible and trusted remote authentication system

The information security domain focuses on needs at all levels in a computing environment either the Internet of Things, Cloud Computing, or any other implementation. Data, devices, services, applications and communication are required to be protected provided by shields working states. Remote authentication is perform different administrative operations an system, Administrators have full access system may pose insider threats. Superusers administrators most trusted persons organisation. “Trust but verify” approach eye superusers administrators. Distributed ledger technology (Blockchain-based data storage) immutable storage scheme provides built-in facility share statistics among peers. ledgers proposed provide visible non-repudiation, which securely records administrators’ authentications requests. presence security, privacy, accountability measures establish trust its stakeholders. Securing electronic processing challenging, i.e., providing services control for resources only legitimate users. Authentication plays vital role systems’ security; therefore, identity management key subjects services. leading cause breaches failure management/authentication systems In this regard, more deterrence than schemes. paper, scheme, “VisTAS,” has been introduced, tenants keeps blockchain.
