摘要
由于移动自组织网的自身特点导致其在实现节点跨域认证时存在诸多困难。基于PKI/CA的认证技术以及分层式的自组织网结构为跨域认证提供了较好的灵活性和安全性。由于控制节点签名密钥对于跨域认证的重要性,文中基于门限技术对其安全防护方案进行了详细论述,通过两种不同的解决方案分别实现了不同条件和环境下控制节点的密钥抗毁。
The special characteristics of mobile Ad-hoc network lead to the difficulties in realizing the cross-domain authentication of network nodes. The PCI/CA-based authentication technology and the hierarchical network structure provide fairly good flexibility and security for cross-domain authentication. However, it is extremely important to control the signature key of each node while doing the cross-domain authentication. This article discusses in detail the safety solutions based on threshold technology for this kind of process. The two solutions described in this article could realize the key survivability of control node respectively under different conditions and different environments.
