摘　　要：在分析P2P网络节点安全问题和JXTA平台具有的安全机制的基础上,构建一个基于JXTA的以节点甄别为目标的安全网络环境,并提出了一种基于信任和推荐的新型信誉模型。分析证明,该信誉模型通过采用信任和推荐两种机制来确定节点的信任度,成功地避免了单点失效问题并有效地遏制了P2P系统中虚假节点的欺骗行为。Based on analyses of the secure limitation of P2P network peer nodes and the secure mechanisms on JXTA platform,in this paper it sets up a safe network environment which aims at nodes discrimination based on JXTA, and also makes a novel reputation model based on trust and recommendation. It is proved by analyses that this reputation model successfully avoids the single peer fail and keeps down the amount of spurious action which caused by the fake peer in P2P system by adopting two mechanisms of trust and recommendation to make sure the trustful degree of peer nodes.
