Proxy Re-encryption Scheme based on the Timed-release in Edge Computing

With the growth of Industrial Internet, various types of data show explosive growth. Data is being moved from the cloud to the edge for computing more frequently and edge computing becomes an important factor affecting the deep application of Industrial Internet platforms. However, the security issue of data transmission sharing is not addressed. Therefore, this paper proposes a security scheme based on timed-release, multi-dimensional virtual permutation, and proxy re-encryption(PRE), to protect the confidentiality of the data during the transmitter; symmetric cryptography is employed to encrypt the transmission data. At the same time, a time server is used, making it impossible for data receivers to get the information about the data before the specified time arrives, it solves the application scenario of data transmission and sharing with timed-release requirements and the efficiency of a large number of data is solved, and the security of data is improved. Finally, the security of the scheme was proved theoretically. Compared to existing PRE schemes, this scheme adds timed-release controlled access, has resistance to ciphertext attacks and end-to-end security features, and uses fewer bilinear pair operations in the algorithm. The performance was tested experimentally and the results show that the scheme improves efficiency while ensuring security and has significant advantages in terms of data security and private data protection.
