IET Software, Volume 2026, Issue 1, 2026.The modern metropolis essentially demands the use of state‐of‐the‐art, real‐time surveillance systems, which should be reliable, scalable, and respectful of privacy at the same time. Critical shortcomings in traditional architectures are single points of failure, poor scalability, frequent data breaches, and inadequately managed privacy.

Group-oriented ciphertext-policy attribute-based encryption with expressive access policy
网络与信息安全学报, 2017 Based on the study of the traditional attribute-based encryption,a scheme called group-oriented ciphertext-policy attribute-based encryption was proposed.In the scheme,the access policy consists of AND-gate and OR-gate.Users were split up into different ...

Ciphertext policy hidden access control scheme based on blockchain and supporting data sharing
Tongxin xuebao, 2022 Objectives: Although the traditional attribute-based encryption scheme achieves one-to-many access control,there are still challenges such as single point of failure,low efficiency,no support for data sharing,and privacy leakage.To solve these problems,a
