AI总结：
本文系统回顾了基于凭证的去中心化信任管理系统的现状，分析了其架构、凭证机制和信任评估模型，指出了该领域面临的关键挑战和研究方向。
摘要：
信任管理系统（TMS）在分布式环境中管理信任至关重要。去中心化系统和区块链的兴起引发了对基于凭证的去中心化信任管理系统（DTMS）的兴趣。本文通过系统性地回顾基于凭证的DTMS，弥合了理论与实践之间的差距。我们通过多个维度分析现有的DTMS解决方案，包括其架构设计、凭证机制和信任评估模型。我们的调查提供了基于凭证的DTMS方法的详细分类，并建立了全面的评估标准来评估DTMS实现。通过广泛分析当前系统和实现，我们识别了该领域中的关键挑战和有前途的研究方向。我们的调查为从事DTMS研究和实践的人员提供了有价值的见解，特别是在访问控制、声誉系统和基于区块链的信任框架等领域。
英文摘要：
Trust management systems (TMS) are crucial for managing trust in distributed environments. The rise of decentralized systems and blockchain has sparked interest in credential-based decentralized trust management systems (DTMS). This paper bridges the gap between theory and practice through a systematic review of credential-based DTMS. We analyze existing DTMS solutions through multiple dimensions, including their architectural designs, credential mechanisms, and trust evaluation models. Our survey provides a detailed taxonomy of credential-based DTMS approaches and establishes comprehensive evaluation criteria for assessing DTMS implementations. Through extensive analysis of current systems and implementations, we identify critical challenges and promising research directions in the field. Our examination offers valuable insights for researchers and practitioners working on DTMS, particularly in areas such as access control, reputation systems, and blockchain-based trust frameworks.
