ENUM的安全性和隐私保护问题探讨

Discussion on ENUM Security and Privacy

电子号码(ENUM)是因特网工程任务组(IETF)中“电话号码映射”工作组提出的一项网络新技术,它把符合E.164标准的电话号码作为用户通信的入口,采用域名服务(DNS)技术和运行框架提供基于电话号码的通用目录服务。DNS是一种开放系统,给ENUM的安全性和隐私保护带来隐患。文中简要介绍ENUM技术及其发展现状,着重分析和探讨了ENUM中存在的安全性和隐私保护问题,并对ENUM中所用的安全协议做了比较。

ENUM (electronic number) is a new network technology put forward by IE TF (Internet Engineering Task Force) Telephone Number Mapping Workgroup. It uses E.164 standard telephone number as the entrance to user communication, and prov ides telephone number based common directory services by using DNS technology an d operation architecture. DNS is a kind of open system which brings hidden troub les to ENUM Security and Privacy. This paper first briefly introduces ENUM techn ology and the present status of its development, and makes an in-depth discussio n and analysis on its security and privacy protection problems. Security protoco ls used for ENUM are then compared.
