ePrint Report: Cryptographic Role-Based Access Control, Reconsidered

Bin Liu, Antonis Michalas, Bogdan Warinschi

In this paper, we follow the line of existing study on cryptographic enforcement of Role-Based Access Control (RBAC). Inspired by the study of the relation between the existing security definitions for such system, we identify two different types of attacks which cannot be captured by the existing ones. Therefore, we propose two new security definitions towards the goal of appropriately modelling cryptographic enforcement of Role-Based Access Control …
