Hybrid mobile ad hoc networks have received increasing attentions due to some attractive features.However, these features such as wireless communication and dynamic topology make it face more challenges in providing secure network services.This paper focuses on the certificate revocation issue which is an important component of certificate management.The existing certificate revocation schemes for mobile ad hoc network either consume more time and accusation overhead to revoke a certificate or need to be improved in terms of revocation accuracy.In this paper, we propose a lightweight certificate revocation scheme for hybrid mobile ad hoc network to achieve a performance trade-off between efficiency and reliability.In particular, to improve the efficiency, the scheme revokes certificate when the accusation weight of the accuser is larger than the accused node; to guarantee the reliability, the revoked nodes are evaluated again by wrong revocation recovery mechanism, so the wrongly revoked nodes will be detected and recovered.Simulation results demonstrate the proposed scheme can achieve a performance trade-off between high accuracy obtained by voting-based scheme and other performance metrics like short revocation time and low overhead obtained by non-voting-based scheme.
