Deploying PKIs in ad hoc networks opens up various issues related to the intrinsic characteristics of these networks. In the literature, many proposals for PKI over ad hoc networks are based on the distribution of the certification authority via a threshold secret sharing scheme. However, these proposals are mostly suitable for managed ad hoc networks. In this paper, the authors propose a self organized peer-to-peer CA. This CA is generic and can suit various contexts of spontaneous ad hoc networks. It does not rely on any central or external entity. The CA's services are carried out by the different participating CA members determined. The proposed protocol has two phases: the bootstrapping phase and the operating phase.
