Abstract

With the flourishing development of the Internet of Things (IoT), IoT devices are becoming increasingly connected with people. IoT devices are constantly collecting and transmitting large amounts of private information, and there is a need for data access control and secure data sharing. Since Ciphertext Policy Attribute-Based Encryption (CP-ABE) is an end-to-end encryption solution, CP-ABE-based access control methods can effectively meet the data security sharing requirements in the IoT environment. However, existing CP-ABE access control methods are difficult to implement data access control. There are no standardized data access control solutions, and redundant storage of data can occur. This study addresses the issue that existing CP-ABE access control methods have difficulty in achieving data permission management. A CP-ABE access control scheme that supports data permission management is designed. To support data permission management, the data is partitioned into key-value pairs. A data permission management policy is designed based on the access control policy, which not only sets the access policy but also specifies the data unit scope of authorized users. The CP-ABE algorithm is used to encrypt the set of encrypted data unit keys in the policy, replacing the redundant storage of data units with keys. This study formulates a standardized data permission management scheme based on the CP-ABE access control scheme, effectively reducing data redundancy storages.
