摘要:

容器具有占用资源少、资源利用率高、启动速度快和弹性能力强等优点,在数据中心云计算资源建设中的应用越来越广泛。相关研究表明,目前容器云存在缺乏可信接入机制的问题,IPv6具有地址空间大和安全性高的特点,基于IPv6构建容器云平台能够建立端到端的透明连接,实现可信接入。针对容器云平台的安全可信问题,文章对IPv6真实源地址验证方法进行改进,将真实用户身份信息嵌入IPv6地址的后64位,同时针对容器多备份且高度动态性的特点,采用哈希加盐的方式生成用户标识,并在IPv6地址中嵌入数据索引,替代原有的加密编码方式,解决因密钥管理和线性匹配导致的效率低下问题。文章还对地址生成流程进行优化,降低了地址解析的时间复杂度,满足容器云平台的地址分配要求。实验结果表明,优化后的IPv6真实源地址验证方法在地址生成阶段效率提升约35%,在地址溯源阶段将时间复杂度从O(n)降到O(1),有效避免了密钥的管理和匹配问题,能够适应容器多备份和高动态环境,提升了容器云平台的内生安全能力。

Abstract:

Container is increasingly used in cloud computing resource management in data center because of its low resource consumption, high resource utilization, fast startup speed, and strong elasticity. Relevant studies have shown that current container cloud lack trustwworthy access mechanism. IPv6 with large address space and high safety can establish end-to-end transparent connection and achieve trustworthy access in container platform. To solve the trustworthy issue of container cloud platform, an improved method for authenticating the real source address of IPv6 was proposed. This method embeded real user identity information into the last 64 bits of the IPv6 address. Meanwhile, to account for the highly dynamic nature of container backups, user identifier was generated based on hash and salt-add algorithm, and the data index was also embedded in the IPv6 address, replacing the original encryption method with low efficiency because of key management and linear matching. By this way, the address generation process could be optimized, the time complexity of address resolution could be reduced, and the address allocation requirements of container cloud platform can be satisfied. Experimental results show that the optimized method could improve authenticating the real source address of IPv6 efficiency by approximately 35% in the address generation stage and reduce the time complexity from O(n) to O(1) in the address tracing stage. It can adapt to highly dynamic container environment and significantly enhance the endogeous security of container cloud platform.
