Abstract
<div class="section abstract"><div class="htmlview paragraph">The current automotive electronic and electrical (EE) architecture has reached a scalability limit and in order to adapt to the new and upcoming requirements, novel automotive EE architectures are currently being investigated to support: a) an Ethernet backbone, b) consolidation of hardware capabilities leading to a centralized architecture from an existing distributed architecture, c) optimization of wiring to reduce cost, and d) adaptation of service-oriented software architectures. These requirements lead to the development of Zonal EE architectures as a possible solution that require appropriate adaptation of used security mechanisms and the corresponding utilized hardware trust anchors.<ol class="list nostyle"><li class="list-item"><span class="li-label">1</span><div class="htmlview paragraph">The current architecture approaches (ECU internal and in-vehicle networking) are being pushed to their limits, simultaneously, the current embedded security solutions also seem to reveal their limitations due to an increase in connectivity. In conjunction with an increasing number of related laws and regulations (such as UNECE R155 and ISO 21434), these drive security requirements in different domains and areas.</div></li><li class="list-item"><span class="li-label">2</span><div class="htmlview paragraph">In this paper we examine the upcoming trends in EE architectures and investigate the underlying cyber-security threats and corresponding security requirements that lead to potential requirements for “Automotive Embedded Hardware Trust Anchors” (AEHTA). We see that communication requirements including increased feature set (such as Authenticated Encryption for Associated Data (AEAD) and Authentication of Associated Data (AAD)) and increased performance requirements significantly impact the architecture of AEHTA. Additionally, we try to point out how new smart solutions could improve overall performance of applications needing security mechanisms.</div></li><li class="list-item"><span class="li-label">3</span><div class="htmlview paragraph">We show, that the overall impact of new security requirements on AEHTA can be categorized into security feature set, safety for security requirements and performance requirements.</div></li></ol></div></div>

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
