Abstract

Attribute-based encryption (ABE) is an important encryption system nowadays, widely used in data storage on cloud computing, as well as in many other applications such as pay TV and file sharing. Attribute-based encryption allows for access control to user data based on attributes. Among the current attribute-based encryption systems, the system proposed by authors Riepel and Wee in 2022 is considered one of the most important. This system is highly efficient and has good security features; however, its drawback is the lack of support for decentralization. In this paper, we propose a solution to enhance the decentralization feature for the Riepel-Wee encryption system. We then provide a comparative analysis of the strengths and weaknesses of our proposed encryption system with some other attribute- based encryption systems that support decentralization features.
Keywords: Attribute-based encryption, decentralized, cloud storage.
