In MANET, we considered solid secrecy requirements regarding secrecy-maintain. For that propose an unobservable secure routing scheme Solid hybrid security protocol to offer an authorised content accessibility and complete unlinkability. Solid hybrid security protocol is uses a combination of group signature and ID-based encryption for the secure route finding. Security analysis described about that solid hybrid security protocol can well protect user privacy against the both inside and outside attackers. For MANET we define stronger privacy requirements regarding privacy-preserving routing. For that an unobservable secure routing scheme USOR has been proposed to offer complete unlinkability and content unobservability for all types of packets. USOR is an efficient combination of group signature and ID-based encryption for route discovery. Security analysis demonstrates that USOR can well protect user privacy against both inside and outside attackers. It implements USOR on ns2, and evaluates its performance by comparing with AODV and EAACK. The simulation results show that USOR has satisfactory performance compared to AODV, but also achieves stronger privacy protection than existing schemes like EAACK.
