MOCA : Mobile Certificate Authority for Wireless Ad Hoc Networks

چکیده
PKI has been recognized as one of the most effective tools for providing security for dynamic networks. However, providing such an infrastructure in ad hoc wireless networks is a challenging task due to their infrastructure-less nature. In this paper, we present these challenges in detail, identify the requirements for such solutions, and propose a practical PKI service for ad hoc networks. We employ threshold cryptography to distribute the CA functionality over specially selected nodes based on the security and the physical characteristics of nodes. The selected nodes that collectively provide PKI functionality are called MOCA (MObile Certificate Authority)s. Using these MOCAs, we present an efficient and effective communication protocol for correspondence with MOCAs for certification services. Results from our simulations verify the effectiveness and the efficiency of our approach.

متن کاملEvaluation of Certificate-Based Authentication in Mobile Ad Hoc Networks
The certificate-based authentication is well studied in wired networks. However, adapting certificatebased authentication protocols to mobile ad hoc networks (MANETs) is a nontrivial task, mainly because, in a MANET, as opposed to conventional wired networks, there typically exists no fixed infrastructure or centralized management. For example, a conventional certificate-based authentication sy...
