摘要
随着信息安全中的信任和认证技术的发展,无线应用的广泛使用,传统密码认证和密钥分发技术在无线信道资源受限的情况下,使用和管理复杂,基于身份加密(IBE)技术能够很好地解决这些新问题。介绍了IBE技术的发展背景和现状,分析了对称加密、PKI和IBE的密钥管理方式,提出了IBE技术在实际应用中需要解决的问题,给出了相应的解决思路。并针对密钥托管与用户私钥安全分发问题,分析和比较了典型解决方案及其适用环境。
With the development of confidence and authentication technologies in information security and the wide application of wireless technology,the application of traditional key authentication and distribution technology is complex and limited, IBE could effectively solve these problems. The development background and present situation of IBE technology is described, the key management technology for symmetric encryption,PKI and IBE is analyzed,the problems of IBE technology in application are presented,and the solutions to those problems are also given. Finally,aiming at the key escrow and the distribution of users＇ private key,the typical solutions and applications are analyzed and compared.
