Golden Jackal Cost Optimized Zero Trust Security with Block-Chain for Intrusion Detection and Prevention in MANET with 5G and NxtG Technology

Abstract

The usage of Fifth-Generation(5G) and Next-Generation(NxtG) technology within MANETs makes new opportunities for achieving reliable, high-speed, and low-latency connectivity. But, the absence of centralized management in MANETs, along with their exposure to security attacks and constrained resources, presents significant drawbacks. This paper proposes a Golden Jackal Cost Optimized Zero Trust Security with Block-Chain Technique (GJCOZTS-BCT) to provide robust and scalable security for MANETs operating under 5G and NxtG infrastructures. The GJCOZTS-BCT eliminates implicit trust within the network through enforcing a zero trust architecture where each node must continuously authenticate their identity and behavior of others before communication. A block-chain protocol is utilized in GJCOZTS-BCT to securely store trust metrics, authentication data, and policy logs, ensuring tamper-proof and transparent trust management. The GJCOZTS-BCT also incorporates a cost optimization engine that balances trust enforcement with resource usage by minimizing computational overhead during routing and access control decisions. By using the advanced capabilities of 5G and NxtG technology, proposed GJCOZTS-BCT ensures secure, real-time, and efficient operations across the MANET. The GJCOZTS-BCT is designed to effectively predict the cyber threats including Sybil, spoofing, and insider attacks in 5G and NxtG technology while maintaining scalability. The simulation of GJCOZTS-BCT is carried out using metrics such as packet delivery rate achieved approximately 95.98%, communication overhead reduced to 18ms, and scalability achieved 95.56% across dynamic MANET environments.
