【摘要】：随着蓝牙等技术的出现,无线自组织网络受到越来越多的关注。无线自组织网络是一种自组织和自适应的网络,它主要有自组织性、多跳式、动态括扑变换快、通信带宽有限、能力受限等特点。正是这些特点使得无线自组织网络更易遭受安全威胁,所以它的安全问题也备受关注。然而由于无线自组织网络的固有特点,使得传统的安全技术不再适用于无线自组织网络。为了使无线自组织网络得到更广泛的应用,无线自组织网络的安全问题迫切希望得到解决。从安全系统中用户的行为流程看,要经历“身份认证”到“加密通信”的过程。其中安全身份认证算法是构建安全系统的第一道防线。为了构建一个基于无线自组织网络并且能够应用到实际的认证算法,本文做了如下工作:1.详细介绍无线自组织网络的安全身份认证技术和RSA-TBOS签密算法,并介绍了该签名算法的安全性证明。接着在这基础上提出适于无线自组织网络的安全身份认证算法。2.最后基于OpenSSL库,对本文提出的安全身份认证算法进行编程实现。而且从随机数的正确性、哈希函数的正确性、RSA的公钥加密和私钥解密正确性,以及RSA私钥签名公钥验证正确性四个方面对认证算法的正确性进行测试。然后在windows环境下对认证算法的运行时间进行测试,再与普通的认证算法进行比较,测试本文提出的安全认证算法是否高效。最后用软件NS-2对路由协议进行仿真来测试认证方案对路由协议性能的影响,验证该方案是否能够应用于无线自组织网络。结论表明该认证算法是高效的,而且能够很好地应用于无线自组织网络。
[Abstract]:With the emergence of Bluetooth and other technologies, more and more attention has been paid to wireless ad hoc networks. Wireless ad hoc network is a kind of self-organizing and adaptive network. It has the characteristics of self-organization, multi-hop, fast dynamic envelope transform, limited communication bandwidth and limited capability. It is these characteristics that make wireless ad hoc networks more vulnerable to security threats, so its security issues are also concerned. However, due to the inherent characteristics of wireless ad hoc networks, traditional security techniques are no longer suitable for wireless ad hoc networks. In order to make the wireless ad hoc network more widely used, the security problem of the wireless ad hoc network is urgently desired to be solved. From the behavior flow of the user in the security system, it is necessary to go through the process of identity authentication to encrypted communication. The security authentication algorithm is the first line of defense to construct the security system. In order to build a wireless ad hoc network and be able to apply to the actual authentication algorithm, this paper does the following work: 1. The security authentication technology and RSA-TBOS signcryption algorithm of wireless ad hoc network are introduced in detail, and the security proof of the signature algorithm is also introduced. Then, a secure identity authentication algorithm. 2. 2 is proposed for wireless ad hoc networks. Finally, based on OpenSSL library, the security identity authentication algorithm proposed in this paper is programmed and implemented. Moreover, the correctness of the authentication algorithm is tested from four aspects: the correctness of random number, the correctness of hash function and the correctness of public key encryption and private key decryption of RSA, and the correctness of RSA private key signature public key verification. Then the running time of the authentication algorithm is tested under the windows environment and compared with the common authentication algorithm to test whether the security authentication algorithm proposed in this paper is efficient or not. Finally, the software NS-2 is used to simulate the routing protocol to test the effect of the authentication scheme on the performance of the routing protocol, and to verify whether the scheme can be applied to wireless ad hoc networks. The results show that the proposed authentication algorithm is efficient and can be applied to wireless ad hoc networks.
