Key Management for Lightweight Ad-hoc Routing Authentication

Abstract

Most lightweight ad-hoc routing authentication protocols based on hash-chain method face the latency issue. This is because the late disclosure of predecessor key in the hash-chain leads to delayed authentication. Moreover, routing authentication approaches usually ignore or assume a prior key management as a working condition. In this paper, we integrate a reliable key management scheme based on threshold cryptography into a lightweight authentication using digital signature to avoid the latency. Our purpose is to provide a full access control solution, from key management to authenticating each traffic packet.
