A survey on caching techniques of the content centric networking (CCN) represented information centric networking (ICN) was given, which categorize the main research idea and methodology. Firstly, the operating principle of ICN caching as well as its key research topics was outlined and the advantage of the ICN using in the wireless networks was analyzed. The research on CCN represented ICN caching deployment scheme design and theory modeling analysis was summarized respectively. Finally, the developments and challenges of ICN caching techniques in the future research was given. The possible research aspects along with the key problems was found, which can provide a useful reference for further study of ICN caching.
