Abstract


Mobile ad hoc networks is a wireless communication mobile networks rely on any prior laying fixed facilities , all network functions including routing, mobility management through the completion of the mutual cooperation of the mobile node . The establishment of the trust relationship is the premise of the mobile ad hoc networks secure communications , to ensure that the system is more safe and reliable operation of great significance . Traditional network PKI digital certificates can be used to establish a trust relationship between the nodes , which requires a trusted third-party authority (CA) to identify the user's identity . Mobile ad hoc networks due to its own characteristics , and can not exist a single CA . Distributed certificate management \The model combines the characteristics of mobile ad hoc networks , threshold secret sharing mechanism to modify and expand the node key component to generate and update mechanism . The model combines the theory of PKI certificates , establish a certificate issued update mechanism , and through the introduction of the allegations threshold , the establishment of a certificate revocation mechanism , making it a complete system . The model contains the end nodes, management nodes , registered RA, the virtual Certification Center CA four components , they are independent and interrelated . Each end of the model node contains two libraries : the certificate library and CRL (certificate revocation list ) library . Model of inter-node communication , communication information system encryption using symmetric encryption , encryption key consultations held to verify the identity of communicating parties . Simulation results show that : the model generates additional network load and node computational suitable for the actual network environment , with a certain application prospects .
