HTAC: Fine-Grained Policy-Hiding and Traceable Access Control in mHealth
IEEE Access, 2020 As an emerging cryptographic primitive, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is suitable for the owner to share his personal health records (PHRs) in mobile healthcare systems (mHealth).

Fine-grain access control for distributed shared memory [PDF]
Proceedings of the sixth international conference on Architectural support for programming languages and operating systems, 1994 This paper discusses implementations of fine-grain memory access control, which selectively restricts reads and writes to cache-block-sized memory regions. Fine-grain access control forms the basis of efficient cache-coherent shared memory. This paper focuses on low-cost implementations that require little or no additional hardware.

Access Policy Sheet for Access Control in Fine-Grained XML [PDF]
, 2005 We propose an access control scheme for developing authorization rules for XML documents, allowing flexible data granularity and authorization propagation. To simplify the complex access control policies in XML, we introduce a new tool: Authorization Policy Sheet (APS). Complex access control rules can be easily described in an APS.

Towards Fine-Grained Access Control in JavaScript Contexts [PDF]
2011 31st International Conference on Distributed Computing Systems, 2011 A typical Web 2.0 application usually includes JavaScript from various sources with different trust. It is critical to properly regulate JavaScript's access to web application resources. Unfortunately, existing protection mechanisms in web browsers do not provide enough granularity in JavaScript access control.

Modelling Fine-Grained Access Control Policies in Grids [PDF]
Journal of Grid Computing, 2015 This paper presents an abstract specification of an enforcement mechanism of usage control for Grids, and verifies formally that such mechanism enforces UCON policies. Our technique is based on KAOS, a goal-oriented requirements engineering methodology with a formal LTL-based language and semantics. KAOS is used in a bottom-up form.

Vigiles: Fine-Grained Access Control for MapReduce Systems [PDF]
2014 IEEE International Congress on Big Data, 2014 Security concerns surrounding the rise of Big Data systems have stimulated myriad new Big Data security models and implementations over the past few years. A significant disadvantage shared by most of these implementations is that they customize the underlying system source code to enforce new policies, making the customizations difficult to maintain ...

What Do Large Language Models Know About Materials?
Advanced Engineering Materials, EarlyView.If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...
