TL;DR: This paper proposes a new password-based user authentication scheme in hierarchical wireless sensor networks that achieves better security and efficiency as compared to those for other existing password- based approaches.

TL;DR: A new authentication scheme for multi-server environments using Chebyshev chaotic map that provides strong authentication, and also supports biometrics & password change phase by a legitimate user at any time locally, and dynamic server addition phase.

TL;DR: This paper proposes a new secure three-factor user remote user authentication protocol based on the extended chaotic maps and presents the formal security analysis using the both widely accepted real-or-random model and Burrows–Abadi–Needham logic.

TL;DR: This paper proposes a new scheme that provides a combined approach of fine-grained access control over cloud-based multiserver data along with a provably secure mobile user authentication mechanism for the Healthcare Industry 4.0.

TL;DR: This paper proposes a new secure and lightweight mobile user authentication scheme for mobile cloud computing, based on cryptographic hash, bitwise XOR, and fuzzy extractor functions, and demonstrates that it is secure against possible well-known passive and active attacks and also provides user anonymity.
