Abstract:
In IBE system, key update and key escrow are difficult problems which couldn’t be well solved. This paper introduces some typical key management schemes for IBE. From engineering application point of view, it compares these schemes from security, system complexity (cost), adaptability and other aspects.
Key words:
Identity based encryption(IBE),
Key escrow,
Key update
摘要： 在基于身份加密(IBE)系统中，密钥托管和密钥更新问题一直没有得到很好的解决。该文介绍了几种典型的IBE密钥管理方案。并从工程应用的角度，分别从安全性、系统复杂度(代价)、适用环境等几个方面对各方案进行了分析比较。
