| 摘要: |
| 由于供应链的应用场景往往需要多个公司的协同，物品追溯服务也就涉及跨组织的场景，因此有必要研究跨组织安全物品追溯的理论和方法。本文提出一个跨组织物品追溯的形式化模型和跨组织物品追溯服务的三个安全属性：可追溯性、可信性和隐私保护；设计一个跨组织安全物品追溯框架，及其中的三个基本协议：发货协议、验证协议和收货协议；本文最后介绍一个满足上述三种安全属性的跨组织安全物品追溯原型系统，并对其进行评估。 |

| Abstract: |
| To solve the data security problem for object tracking in a cross-organizational supply chain, a formal model with three security properties, i.e., accountability, trustworthiness, and privacy protection, is introduced. The model may be implemented with three protocols introduced in the paper, namely goods issuing, validation, and goods receipt protocols. The above formal model and the associated protocols are evaluated through a prototype implementation described in the paper, along with an analysis of its performance. |
