发布/订阅系统已经在许多应用中得到了很好的研究。然而，现有方法的密钥管理效率不够高。因此，针对云场景下发布/订阅系统，提出了一种高效的基于二分派生的密钥管理方案。该方案将订阅间隔导出为两个二分法订阅间隔。因此，密钥管理成本是以2为基数的随订阅间隔长度的对数增长。与现有方法的线性增长相比，我们的方案在云场景下的大数据处理效率要高得多。实验结果表明，该方案在密钥管理方面的性能明显优于已有的方法。
Publish/subscribe system has been well-studied for many applications. However, the key management of existing methods is not efficient enough. Therefore, we propose an efficient key management scheme based on dichotomy derivation for publish/subscribe system in cloud scenarios. The scheme derives a subscription interval to two dichotomy subscription intervals. Thus, the key management costs are logarithmic growth in base 2 with the length of subscription interval. Comparing with the linear growth of existing methods, our scheme is much more efficient for big data in cloud scenarios. Experimental results show that our scheme significantly outperforms existing methods in key management.
