Abstract

In ad hoc network, it is very crucial to issue certificates safely in the self-initialized scheme where the system authority exists only at the beginning of the network operation. In order to solve this problem, early studies have presented some suggestions by removing the system authority itself and using certificate chain, or by making nodes act as system authorities for issuing other nodes' certificates. In this paper, using proxy and threshold signatures, we introduce a certificate issuing scheme that can solve many problems in the previously proposed solutions. We demonstrate our scheme's performance through the simulation results. Also, we discuss the security value of our scheme's in various aspects.
