Abstract Security of Mobile Ad hoc Networks (MANETs) is still a hard problem after years of research. We propose a new design approach and a framework for securing a practical type of MANETs. The framework is named PAPA‐UIC , short for Pre‐planned Ad‐hoc Proactive Approach Using Identity‐based Cryptography . In proactive approach, the system starts from a secure status and fortifies this status by protecting packets using cryptography and updating cryptographic keys periodically or when necessary. The proposed scheme addresses the interdependency cycle of secure routing and security services by combining secure routing and key management in one framework. The framework proposes a secure routing protocol (SRP) using identity‐based cryptography and solutions to general problems of identity‐based cryptography. The routing protocol has several improvements over existing ones. The novel ideas to solve key escrow, identity disclosure and identity revocation issues can be integrated into the framework, and can be transplanted to other environments as well.
