In this paper, the authors present a novel scheme that provides high level of security and privacy in a Wireless Mesh Network (WMN). They combine an approach of network coding with multiple layered encryption of onion routing for a WMN. An added superior feature provides higher level of security and privacy. Sensitive network information is confined to 1-hop neighborhood which is available anyways in a wireless medium with nodes using a bivariate polynomial. The only routing information divulged to a relay node is about next hop. No plain text is ever transmitted and all data can only be decrypted by its source and destination.
