Secure search query routing is a long-standing problem in distributed networks, which has often been addressed using "all-or-nothing" approaches, that require either full anonymity and encrypted routing or full trust on the routing nodes. An important problem with secure routing is how to guarantee the search query is transmitted in an expected way. In this paper, we tackle the problem of secure routing by considering a generic policy-driven routing approach, and focus on the steps required to

We present an efficient and effective verification method for query routes, that is agnostic to the specific routing algorithm being used and achieves strong security guarantees. We cast our approach in the context of content dissemination networks (CDN) and show through experimental evaluations the performance of our approach.
