| 摘 要： | IPv6通过EUI-64实现无状态地址自配置的同时也带来用户隐私问题。为此，IETF又引入RFC3041标准以产生有特定时效的无状态随机IPv6地址，提高用户的安全性，但这种元状态随机自配置地址也给IPV6包分类及网络扫描等算法的优化设计带来新的困扰。文章通过熵理论对真实IPv6地址进行随机性分析，并通过逾10万样本数据的随机测度计算后发现：RFC3041产生的IPv6地址具有固定比特恒为0的随机特性。

| Abstract: | 64-bit extended unique identifier （EUI-64） enables IPv6 address to achieve stateless self-configuration, hut users＇ privacy posts a problem. In order to improve the users＇ security, IETF introduces RFC3041 standard to generate stateless random IPv6 address which has a specific aging, but the stateless self-configured address perplexes the optimization design of IPV6 packet classification and network scanning algorithms. With the randomness analysis of real IPv6 address based on entropy theory and the randomness measure calculation of more than 100,000 samples, the randomness characteristics that a fixed-bit is equivalent to zero is found. |
