Enhancing Security Authentication in Mobile Ad Hoc Networks (MANETs) Using ETESLA-ACK

Abstract

Security authentication in Mobile Ad Hoc Networks (MANETs) remains a critical challenge due to their decentralized and dynamic nature. This research proposes an enhanced authentication scheme leveraging ETESLA-ACK (Enhanced Timed Efficient Stream Loss-tolerant Authentication with Acknowledgments). Nodes in the MANETs generate Authentication Tokens (AT) containing message payloads, expiration times, and digital signatures. Recipient nodes verify tokens to ensure message relevance and authenticity. Periodic key renewals and group key updates bolster security. This approach enhances MANET security by providing robust authentication, message integrity, and secure key management while mitigating vulnerabilities. Simulation results demonstrate its effectiveness in safeguarding MANET communications.
