摘　　要：作为一种新型的无线移动网络,移动自组网(mobileadhocnetwork,MANET)的安全是现在主要的研究方向。MANET网络不同于传统的网络,因此需要一些新的安全机制。文章简要介绍了MANET网络体系结构特点所面临的问题和需要达到的安全目标,提出了一种基于中国余数定理的分布式门限签名方案,该方案与MANET的特性非常一致。文章还给出了一个采用RSA公钥系统的数字签名算法。分析表明,这种方案具有较好的计算性能。Mobile ad hoc network （MANET） is a new kind of wireless mobile. The security of MANET is a hot research field. Because MANET is different from the traditional network, some new security mechanisms must be used. This paper introduces the characteristics of MANET structure, the problems and the required security goals. Then, a new distributed threshold MANET sigaature scheme is proposed, and it is in accordance with the characteristics of MANET very much. Later, a signature arithmetic using RSA system is proposed. By analyzing, the scheme is proved to be good in computatioaal performance.
