Abstract
En 中文
In today's world, Cyber-Physical Systems (CPS) play a key role in areas like smart homes, transportation, and healthcare, where lightweight IoT devices are used to monitor and control activities. As the number of IoT devices keeps growing, so does the amount of data they generate. This calls for scalable computing and storage solutions, which are often provided using fog and cloud technologies. However, applying secure and efficient access control in these decentralized and resource-limited environments is still a major challenge. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) allows fine-grained access control, but existing multi-authority schemes do not support dynamic update in user attributes-something that is important in real-life CPS, where user roles often change. Also, the heavy computations required in CP-ABE can slow down low-power IoT devices. To solve these issues, we propose SAMIT, a CP-ABE scheme with multiple authorities that supports efficient attribute updates and is designed for embedded systems. Our scheme uses fog nodes to handle complex computations, reducing the load on resource-constrained IoT devices. Security and performance results show that SAMIT is secure and suitable for CPS with limited device resources.
