Research on the Issuing and Management Model of Certificates based on Clustering Using Threshold Cryptography in Mobile Ad Hoc Networking

A mobile ad hocnetwork(MANET) is a network where a set of mobile devices communicate among themselves using wireless transmission without the support of a fixed network infrastructure. The use of wireless links makes MANET susceptible to attack. Eavesdroppers can access secret information, violating network confidentiality, and compromised nodes can launch attack from within network. Therefore, the security for MANET depends on using the cryptographic key, which can make the network reliable, In addition, because MANET has a lot of mobile devices, the authentication scheme utilizing only the symmetric key cryptography can not support a wide range of device authentication, Thereby, PKI based device authenticatioo technique in the Ad Hoc network is essential and the paper will utilize the concept of PKI. Especialy, this paper is focused on the key management technique ot PKI technologies that can offer the advantage of the key distribution, authentication, and non-reputation, and the issuing and 'managing technique of certificates based on clustering using. Threshold Cryptography for secure communication in MANET.
