HoBACDSL: HoBAC-focused Access Control Domain Specific Language
Bibliographic record
Abstract
Access control (AC) in IoT (Internet of Things) systems presents significant challenges. These systems are evolving, heterogeneous, and dynamic, combined with the lack of appropriate tools to specify and design Access Control Policies (ACP). Despite various proposals, complexity persists, especially in restrictive environments like IoT. In this perspective, Higher-Order Attribute-Based Access Control (HoBAC) was proposed as a general AC model that extends Attribute Based AC (ABAC). It allows the design of flexible AC models and policies applicable to IoT and non-IoT systems. The work presented in this paper focuses on addressing the need for tools to support the adoption of HoBAC for IoT systems by proposing HoBACDSL, a Domain Specific Language (DSL). HoBACDSL abstracts the complexities of HoBAC and makes its concepts more accessible. We illustrate how this DSL is concretely used to specify, and generate AC policies in the Extensible Access Control Markup Language (XACML) standard for a Smart Home use case.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
