用于物联网的轻量级可净化属性加密方法
By generating a private key pair and a public attribute key for the recipient, the sender performs offline and online encryption, the cloud platform cleans up the ciphertext, and the recipient performs partial and complete decryption. This solves the problems of high computing costs and unreliable servers in the Internet of Things (IoT), and achieves lightweight and cleanable attribute encryption, which is suitable for IoT scenarios.

AI Technical Summary
Existing attribute-based encryption technologies are computationally expensive in the Internet of Things (IoT), and outsourced decryption servers are not entirely trustworthy. Therefore, how to prevent servers from maliciously tampering with ciphertext and reduce the computational burden on senders and receivers, and how to achieve a lightweight and clean attribute encryption option, are important research goals.
The method employs a private key pair and a public attribute key generated for the recipient. The sender performs offline and online encryption, the cloud platform cleans the ciphertext, and the recipient performs partial and full decryption. The computational burden is reduced by using symmetric encryption methods, and the correctness of the decryption is ensured by verifying the results.
It achieves privacy-preserving, lightweight, and highly secure attribute encryption, reducing the computational burden on both the sender and receiver, preventing unauthorized communication, and is suitable for IoT scenarios.
