Passive attacks have caused a great threat to Wireless Sensor Networks (WSN), therefore the research of communication nodes and the stealthiness of communication relationship is crucial. Due to the problem of node hidden mechanism, a secure anonymous routing named Node-Uncorrelated Pseudonym Pairwise Mechanism (NUCPP) is proposed in this paper. Instead of using the traditional pseudonym node correlation properties, the distribution methods, the specific node of WSNs characterized by the node-correlated pseudonym, NUCPP has a good performance for defending passive attacks, a node-uncorrelated pseudonym pairwise mechanism, an inter-region multipath routing algorithm and an intra-region circular routing algorithm are adopted in it to ensure anonymity of routing. The Analysis shows that NUCPP can fundamentally eliminate the security risks brought by the node-correlated pseudonym, thus effectively guarantee the confidentiality of the node identity.
