IET Information Security, Volume 2024, Issue 1, 2024.Ciphertext‐policy attribute‐based encryption (CP‐ABE) is a cryptographic scheme suitable for secure data sharing on cloud storage. The CP‐ABE based on lattice theory has the property of resisting quantum attack. Some data objects uploaded to the cloud by the same data owner may cause conflicts of interest, or their combination may expose sensitive ...

Secure Sharing of Electronic Medical Records Based on Blockchain
International Journal of Distributed Sensor Networks, Volume 2024, Issue 1, 2024.As network technology advances and more people use devices, data storage has become a significant challenge due to the explosive growth of information and the threat of data leaks. In traditional medical institutions, most medical data is stored centrally through cloud computing technology in the institution’s data center.

Role Mining with Probabilistic Models [PDF]
arXiv, 2012 Role mining tackles the problem of finding a role-based access control (RBAC) configuration, given an access-control matrix assigning users to access permissions as input. Most role mining approaches work by constructing a large set of candidate roles and use a greedy selection strategy to iteratively pick a small subset such that the differences ...

Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]
, 2014 The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Access Control for Hierarchical Joint-Tenancy [PDF]
WSEAS Transactions on Computers, June 2006, Issue 6, Volume 5, p.
1313-1318, 2006 Basic role based access control [RBAC] provides a mechanism for segregating access privileges based upon a user's hierarchical roles within an organization. This model doesn't scale well when there is tight integration of multiple hierarchies. In a case where there is joint-tenancy and a requirement for different levels of disclosure based upon a user ...
