摘　　要：针对多层网络安全认证过程中,各层之间缺少统一的认证规则,常规身份认证方法的准确性易受到多层之间的建模误差与外界扰动的影响,造成认证失败。提出了一种基于OPNET平台非连续对数求解的多层网络身份认证方法。把多层无线传感网络的身份认证问题,转换成非连续对数求解问题,并且引入了数学中的椭圆曲线群观点,对传感网络多层机制设立统一的身份认证机制,从而提高身份认证的准确性;采用OPNET对身份认证方案进行测试。实验结果表明,这种方案可以达到实际的无线传感网络对安全性的要求,具有很强的实用价值。For sensor network security certification process, the lack of unified certification rules between each layer, the accuracy of the conventional identification methods are susceptible to the influence of modeling error and external disturbance between the layers, the authentication failed; Proposed a multi-layered identity fusion technology of sensor network technology seriously, this method is the multi-layer authentication problem of wireless sensor network is converted into solving discrete logarithm problem, and introduced the elliptic curve group in the mathematical point of view, the sensor network multilayer mechanism set up a unified identity authentication mechanism, so as to improve the accuracy of the identity authentication; Using OPMET testing authentication schemes, the experiment results show that the scheme can achieve the actual wireless sensor network to security requirements, have very strong practical value.
