Lightweight Integrity Preserving Scheme for Secure Data Exchange in Cloud-Based IoT Systems

The information obtained from external sources within the cloud and resulting computations are not always reliable. This is attributed to absence of tangible regulations management on part owners. Although numerous techniques for safeguarding securing have been developed, security hazards in still problematic. could potentially pose a significant challenge effective adoption utilization technology. In terms performance, many existing solutions affected by high computation costs, particularly auditing. order reduce auditing expenses, this paper proposes well-organised, lightweight system through enhanced integrity checking. proposed technique implements cryptographic hash function with low-cost mathematic operations. addition, explores role semi-trusted server regard smart device users. facilitates formal prior distribution IoT-cloud system. Essentially, validation stored exchanged environment. results show that offers features such as capability, key management, privacy, decreased sufficient users, one-time provision, degree accuracy. method exhibits lower complexity storage expenses compared those other bilinear map-based systems.
