As a new generation of network architecture with subversive changes to traditional IP networks, Content Centric Networks (CCN) has attracted widespread attention from domestic and foreign scholars for its efficient content distribution, multi-path and secure routing features. The design architecture of CCN network has many advantages. However, it is also easily used illegally, which brings certain security problems. For example, objectified network resources which include requesters, publishers, content and node routes, are faced with many security threats, such as privacy attribute disclosure, privacy detection, content information disclosure, and spoofing and denial of service attacks. A node routing security scheme based on dynamic reputation value is proposed for the security problem of node routing. It is convenient for detecting node routing attacks and defending in time. And it could provide security for the Content Centric Networks node routing without affecting the node routing advantages and normal user requests.
