CCN中一种改进的面向隐私保护的缓存策略
Improved Caching Strategy for Privacy Protection in CCN
摘要
Abstract
Content-Centric Network(CCN)is a new network architecture, but the mode of router caching packets brings the risk of privacy leakage to users. This paper proposes a dynamic regional collaborative caching strategy for privacy pro-tection. It is designed to give consideration to both the privacy protection of users and the improvement of network perfor-mance. From the perspective of information entropy, this strategy aims at improving the uncertainty of users’request infor-mation. By storing content in the corresponding cache node of high hiding coefficient, it increases the difficulty for attackers to determine the requesting users. The contents are stored in the way of dynamic regional collaboration, which increases the attribution uncertainty of cache contents to make it more difficult for attackers to locate packets. Simulation results show that this strategy can reduce the content request delay and improve the cache hit ratio.关键词
