Abstract To solve the security problems in the space-air-ground integrated network, this paper proposed a scheme using routing evidence to defend against flooding attacks and grey hole/black hole attacks. The scheme can detect malicious nodes in the ad-hoc network to guarantee the security and reliability of routing. It resolved the shortcomings of the existing schemes and could be adaptively applied in the interruption and delay tolerant network such as the space-ground integrated network. A simulation platform was built in this study, and according to the verification, the proposed scheme can detect more than 90% of the malicious nodes, proving its significant effectiveness.
