Optimal Re-encryption Strategy for Joins in Encrypted Databaseshat column that will result in the minimum number of re-encryptions even under an unknown schedule of joins. Naive strategies may perform too many or even infinitely many re-encryptions. We provide two strategies that allow for a much better performance. In particular the asymptotic behavior is .(..施魔法 发表于 2025-3-29 02:24:10
Access Control and Query Verification for Untrusted Databasesowner lacks direct control over the hardware and the software running at the server, there is a need to ensure that the data are not read or modified by unauthorized entities. Even though a simple encryption of the data before transferring it to the server ensures that only authorized entities who h宣誓书 发表于 2025-3-29 03:39:13

A Model for Trust-Based Access Control and Delegation in Mobile Cloudsssing subjects may dynamically change, resources requiring protection may be created or modified, and a subject’s access requirements to resources may change during the course of the application execution. Cloud tenants may need to acquire permissions from different administrative domains based on tCLIFF 发表于 2025-3-29 11:48:59

Towards User-Oriented RBAC Modelnstruct the given permission assignments, and the other is user-oriented approximate RMP, which tolerates a certain amount of deviation from the complete reconstruction. The extra sparseness constraint poses a great challenge to role mining, which in general is already a hard problem. We examine som
