Secure role based access control systems using aspect-orientation designing [PDF]

, 2009
Security system designs are required to be flexible enough to support multiple policies. A security policy model always develops; accordingly, the design of a security system using that policy model should reflect the changes.

A Private Blockchain and IPFS‐Based Secure and Decentralized Framework for People Surveillance via Deep Learning Techniques

IET Software, Volume 2026, Issue 1, 2026.
The modern metropolis essentially demands the use of state‐of‐the‐art, real‐time surveillance systems, which should be reliable, scalable, and respectful of privacy at the same time. Critical shortcomings in traditional architectures are single points of failure, poor scalability, frequent data breaches, and inadequately managed privacy.

A Novel Role-based Access Control Model in Cloud Environments

International Journal of Computational Intelligence Systems, 2016
In Cloud environments, the relationship between resources and users is more ad hoc and dynamic. The role-based access control (RBAC) model is an appropriate access control model for Cloud environments.

Securing End‐To‐End Encrypted File Sharing Services With the Messaging Layer Security Protocol

Concurrency and Computation: Practice and Experience, Volume 37, Issue 27-28, 25 December 2025.
ABSTRACT Secure file sharing is essential in today's digital environment, yet many systems remain vulnerable: if an attacker steals client keys, they can often decrypt both past and future content. To address this challenge, we propose a novel file‐sharing architecture that strengthens post‐compromise security while remaining practical.

Event-driven RBAC

Journal of Computer Security, 2015
Context-aware access control systems should reactively adapt access control decisions to dynamic environmental conditions. In this paper we present ERBAC – an event-driven extension of the TRBAC model that allows the specification and enforcement of general reactive policies – and its implementation.

Authorization recycling in hierarchical RBAC systems [PDF]

ACM Transactions on Information and System Security, 2011
As distributed applications increase in size and complexity, traditional authorization architectures based on a dedicated authorization server become increasingly fragile because this decision point represents a single point of failure and a performance bottleneck.
