Web15 de jun. de 2024 · In this paper, we introduce a Multi-Dimensional Access Control (MD-AC) scheme for dynamically authorizing and revoking users in the cloud with multiple authorities. The experimental results indicate that MD-AC can evaluate access requests within reasonable and acceptable processing times. WebFrom the previous work, Shen and Chen 1 proposed a scheme in 2002 to have each class obtain a public and a private key for access purposes. This scheme was developed based on discrete logarithm 2 and Newton’s polynomial interpolation. 3 However, the scheme is not good enough for security. In the following year, Hsu and Wu 4 pointed out the security …
