The SECURE SDN WITH API MANAGEMENT AND ABAC USING BLOCKCHAIN-BACKED CLOUD-NATIVE NETWORK SLICING: HMAC VERIFICATION

API MANAGEMENT AND ABAC USING BLOCKCHAIN-BACKED CLOUD

Abstract

BACKGROUND: The development of 5G networks has made it increasingly difficult to maintain effective and safe network management. Innovative security solutions are needed due to the complexity of device heterogeneity and huge data flow. By enhancing security, transparency, and dynamic resource management, blockchain, SDN, ABAC, and HMAC have the ability to address these issues.

METHODS: ABAC for attribute-based access control, HMAC for message integrity, blockchain for tamper-proof transaction records, SDN for flexible control, and API management for safe interactions are all integrated into the system. These elements work together to provide secure, scalable, and effective 5G network slicing.

OBJECTIVE: The main objective is to use blockchain, SDN, ABAC, and HMAC to improve 5G network security, scalability, and agility. The technology intends to develop a more transparent, efficient, and reliable infrastructure for 5G and future networks such as 6G by optimizing network slicing and securing API interactions.

RESULTS: Comparing the suggested system to conventional techniques, it performed substantially better, exhibiting 96.6% accuracy, 95.8% precision, and 93.1% recall. This improved resource management, security, and scalability. Our findings demonstrate the system's improved security and efficacy in managing 5G networks.

CONCLUSION: This blockchain-based cloud-native network slicing solution provides an architecture that is flexible and scalable for future networks, including 6G, while effectively addressing security concerns related to 5G. It improves overall security, network agility, and resource optimization by combining SDN, HMAC, ABAC, and blockchain; this makes it a strong solution for changing network settings.
