中文摘要:
      NDN网络架构的安全机制构建在信息本身,因此NDN中对传输的数据必须采取有效的签名和加密措施,否则攻击者可以随意获取数据或发送虚假内容,这将成为NDN网络的最大安全隐患。文中针对NDN的安全隐患,设计出一种轻量级加密算法来解决NDN网络架构的安全问题,详细分析了该算法每个步骤的含义和目的,以及它在各种攻击方式下的安全性,同时对算法进行了优化,提高了算法的运行效率。并且在ndnSIM下嵌入该算法进行仿真,验证了数据从发布者开始是以密文方式进行传输,具有机密性;收到数据后能正确地验证发布者的身份,具有认证性;并正确地解出明文和验证数据是否有改动,具有完整性;再分别对攻击方式中的数据内容篡改和身份伪装进行了仿真,验证了对传统网络攻击防范的有效性。
英文摘要:
      NDN security mechanism lies in the information itself, and the effective signature and encryption must be given to the data transmitted in NDN , otherwise the attacker can get data or send them at will. In view of this security problem, a lightweight encryption algorithm is designed. The meaning and purpose of the each step of the algorithm and security under various attack modes are analyzed in detail. The algorithm is optimized to improve its efficiency and is embedded in ndnSIM for simulation. The verified data are transmitted in encrypted way from the publisher and the identity of the publisher can be verified correctly after receiving the data, and the change of plaintext and the verification data can be correctly solved. The effect of the algorithm on confidentiality,authentication , integrity and efficiency are verified.
