移动自组网中一种新的混合认证协议

在现有的面向移动自组网环境的认证方案中，分布式认证的安全性高，但其认证成功率低，尤其是在大规模移动自组网中。针对这一问题，该文提出一种将分布式认证和链式认证有机结合的混合认证方案，前者用于证书管理，后者用于身份认证。理论分析表明，在保证安全性的前提下，该方案提高了协议的可扩展性和认证成功率。

Novel Hybrid Authentication Protocol for Mobile Ad-Hoc Networks

Distributed authentication scheme has high security among the existing authentication schemes for Mobile Ad-Hoc Networks (MANETs). However, its success ratio for authentication is low, especially in large-scale MANETs. In order to tackle this problem, this paper proposes a hybrid authentication scheme which combines distributed authentication with chained authentication. The scheme uses the distributed authentication for managing certificates, and the chained authentication for authenticating the corresponding nodes. Theoretical analysis shows that, compared with existing authentication schemes, the scheme is more scalable and can increase the success ratio for authentication, without sacrificing the security requirement.
