SECURE AND COMPLIANT DATA MOVEMENT FOR SENSITIVE MILITARY OPERATIONS

To reduce cybersecurity risks and maintain operational integrity, the growing amount of sensitive military data calls for safe and legal data transfer protocols.Mission-critical activities are seriously in danger from traditional data transmission systems' susceptibility to illegal access, manipulation, and regulatory non-compliance.By strengthening data integrity, implementing access control, and boosting traceability, the use of blockchain technology provides a solid answer.However, scalability, transaction efficiency, and conformance to changing military requirements are frequently issues with current platforms.To overcome these obstacles, this paper suggests a system for safe data transfer powered by blockchain technology.To strengthen security, the system uses decentralized ledger verification, Role-Based Access Control (RBAC), and cryptographic encryption.To maximize transaction speed while adhering to regulatory requirements like FISMA, NIST, and CMMC, a lightweight blockchain architecture is used.Additionally, a real-time tamper-detection technology is incorporated to detect and prevent unwanted data alterations.Significant gains in system efficiency and data security are shown by the experimental findings.While data transfer speed rises from 900 Mbps to 1450 Mbps, encryption time per 100 MB of data decreases from 12 seconds to 10 seconds.Following blockchain integration, the average daily number of identified tampering attempts drops from 45 to 18, indicating improved data integrity.Controlled access to classified material is ensured Shiva Kumar Vuppala https://
