Some important requirements of key distribution schemes for many emerging applications involving resource constrained devices (for example, ad hoc and sensor networks) are 1) low complexity; 2) the ability to support unmediated establishment of security associations and 3) scalability. We propose a novel key distribution scheme based on an elegant scheme proposed by Leighton and Micali [1]. While the scheme in [1] was intended to be an alternative to Kerberos (employing a trusted server for
