Abstract

Attribute-based encryption in cloud storage enables fine-grained access control and enhances data security. Hierarchical attribute-based encryption schemes reduce computational and storage costs by constructing hierarchical access control strategies. However, existing schemes fall prey to collusion attacks due to parameter settings in the hierarchical access control structure and face high complexity when handling files with slightly different access policies. To address these issues, this paper proposes a scalable hierarchical attribute-based encryption algorithm that resists collusion attacks. The algorithm allows hierarchical nodes to extend during encryption, enabling files with different access policies to share the same hierarchical nodes and simplifying the encryption process for files with minor policy differences. The introduction of user identity noise vectors binds the intermediate values during decryption to individual users, preventing them from extracting sensitive information through collusion. The security analysis demonstrates that the algorithm remains secure under the CPA model. Experimental results show that the algorithm effectively resists collusion attacks while maintaining low performance overhead and significantly enhances efficiency when handling files with slightly different access policies.
