• Abstract: This study examines the performance and structural differences between the two primary standards for Security Credential Management Systems (SCMS) in Vehicular-to-Everything (V2X) communication: the North American IEEE standards and the European ETSI standards. It focuses on comparing their respective Public Key Infrastructure (PKI) architectures, certificate application workflows, and the formats of request/response messages used during certificate applications. The research includes a theoretical analysis of message length and security features inherent in each standard. Additionally, practical implementations of both systems are conducted to evaluate their efficiency in certificate management processes. Based on the findings, the study provides recommendations to guide future development of SCMS.

  We propose Evidence-Centered Benchmark Design (ECBD), a framework which formalizes the benchmark design process into five modules. Each module requires benchmark designers to describe, justify, and support benchmark design choices. Our analysis reveals common trends in benchmark design and documentation that could threaten the validity of benchmarks' measurements.

  Word-Level Auto-Completion (WLAC) plays a crucial role in Computer-Assisted Translation. It aims at providing word-level auto-completion suggestions for human translators. We introduce a measurable criterion to answer this question and discover that existing WLAC models often fail to meet this criterion. We propose an effective approach to enhance WLAC performance by promoting adherence to the criterion.
