Efficient Key Management System Based Lightweight Devices in IoT

The Internet of Things (IoT) has changed our lives significantly. Although IoT provides new opportunities, security remains a key concern while providing various services. Existing research methodologies try to solve the and time-consuming problem also exists. To those problems, this paper proposed Hashed Advanced Encryption Standard (HAES) algorithm based efficient management system for internet-based lightweight devices in networks. method is mainly divided into two phases namely Data Owner (DO) User (DU) phase. DO phase consists processes authentication secure data uploading. In authentication, registration process three KGC, SCC DVC. Key Generation Center (KGC), device ID converted 128-bit hash using Point on Curve Fowler–Noll–Vo (PoC-FNV) algorithm. DVC, Access Policy (DAP) created by selected attributes which turn Chen Chaotic Chimp Optimization Algorithm(CCCOA). Thus, information stored blockchain. If person an authorized, then securely uploaded cloud server HAES. DU phase, sends access request blockchain forwards DO, if accepts obtains DAP. Finally, performance compared with existing methods attains better result than methodologies.
