| 摘要: |
| 内容中心网络（CCN）是一种革命性的网络架构，采用内容路由、网内缓存等技术来提高网络中的内容分发效率，但其自身的结构特点使之面临很多的安全问题。通过对CCN网络工作机制的研究，分析了CCN面临的非授权访问、隐私泄露、泛洪攻击等安全风险；然后，总结了每种安全风险的解决方案及各自优缺点；最后，展望了未来的研究方向。 |

| Abstract: |
| Content-Centric Networking(CCN) is a revolutionary network architecture which uses named-based routing and in-network caching to improve the content distribution efficiency,but it faces many security problems because of the structural characteristics.Through researching the mechanism of CCN,this paper analyzes the security threats the system faces,such as unauthorized access,privacy leak and flooding attack,and then summarizes corresponding solutions and their respective advantages and disadvantages. Finally,it provides future research directions. |
| Key words: content-centric networking security threats access control privacy-preserving flooding attack |
