Abstract

An authentication service is one of the the most fundamental building blocks for providing communication security. In this paper, we present the MOCA (MObile Certificate Authority) key management framework designed to provide authentication service for ad hoc wireless networks. MOCA is a distributed certificate authority (CA) based on threshold cryptography. We present a set of guidelines for a secure configuration of threshold cryptography to maintain strong security. MOCA utilizes a carefully selected set of mobile nodes to function as a collective certificate authority while the MOCA nodes are kept anonymous. Equipped with a novel routing protocol designed to support the unique communication pattern for certification traffic, MOCA achieves high availability without sacrificing security. Both the security of the framework and the operational performance is evaluated with rigorous analysis and extensive simulation study.
