MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202511132818 A) filed by Sr University, Warangal, Telangana, on Dec. 29, 2025, for 'a lightweight hierarchical multi-authority attribute-based encryption system with chaotic authentication and time-controlled re-encryption for secure context-aware data sharing in fog computing environments.'
Inventor(s) include Ms. Mankali Priyadarshini; and Dr. Shanker Chandre.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a secure, scalable, and context-aware data sharing system designed for fog computing environments, particularly in resource-constrained and latency-sensitive domains. The system integrates a lightweight attribute-based encryption framework with a hierarchical multi-authority key management structure to enable fine-grained access control without reliance on computationally intensive cryptographic operations. A dual access policy mechanism is employed to evaluate both static user attributes and dynamic contextual conditions such as time, location, and device identity at the time of access. The invention further incorporates a chaotic group-based authentication mechanism using Chebyshev chaotic maps to provide lightweight and scalable user verification. Additionally, a time-controlled delegated re-encryption capability allows fog servers to autonomously update access policies and re-encrypt data based on predefined temporal conditions without data owner intervention. Collectively, the invention provides an efficient, adaptive, and secure framework for managing sensitive data in distributed fog and edge computing environments."
