Abstract: In order to build security and trusted MANET，we must take into account the characteristics of itself.At present，
most research on security certification mainly use center certification server to send certificate to users，and less consider the
characteristics of self-organization about MANET，so it is difficult to deploy network rapidly.Combining the characteristics of
MANET，a novel self-organization on-demand certification architecture is proposed in this paper，and which does not need
center certification server，and make full use of node’s function to complete authentication with good scalability.

摘要： 构建安全可信的MANET 必须考虑到其自身的特性。目前关于MANET 的安全认证研究大多是利用中心认证服务器为用户颁发证书，较少考虑到MANET 自身的自组织特点，很难完成网络的快速部署。结合MANET 的特性，提出一种自组织按需式认证方案。该方案不需要中心认证服务器，充分利用节点自身功能，在完成身份认证的同时具有良好的伸缩性。
