摘　　要：随着云计算等互联网应用的兴起,个人数据更多地存储于网络上,其数据安全面临着极大挑战,传统的数据加密方式有时候存在加密密钥不能及时销毁的问题,存在着安全隐患。针对当前个人网络数据安全问题,采用Chord和Kademlia两种P2P协议设计了个人应用数据的自销毁协议,利用P2P协议固有的扰动特性进行个人网络数据的自动销毁数据,使用OMNEST仿真软件进行了两种协议对数据自销毁的性能分析,其仿真结果表明使用Kademlia协议的数据自销毁性能更优。With the rise of cloud computing and other Internet applications, personal data is increasingly stored on the network, and data security is confronted with great challenge. In the traditional data encryption, the key sometimes could not be timely destructed, and thus security risks still exist. With Chord and Kademlia P2P protocols the two data self-destruction protocols for the personal network data security are designed, the inherent disturbance characteristics of P2P protocols are used to implement automatic destruction of personal network data. By simulation with OMNEST simulation software, the performances of these two protocols in data destruction are analyzed, and simulation results show that the protocol with Kademlia protocol is better in data self-destruction performance.
