摘要
随着计算机和网络的普及应用,计算机终端自身的安全引起人们的关注,可信计算技术从一个新的视点解决终端的安全问题,已经成为信息安全领域研究的热点。针对目前移动终端软件更新身份认证存在的安全问题,提出基于可信计算技术的解决方案。方案中应用TPM的封存,PCR签名等安全功能实现移动终端的身份认证机制,提出基于DH密钥交换协议和IBE协议的下载方案,解决移动终端平台的身份认证和可信性问题。
PC and network are used so widely that the security of them attracts much attention.Trusted computing technology that is a hot topic in the field of information security provides a solution from a fresh viewpoint.The existing software update of mobile terminal has security weaknesses for identity authentication.Hence new solutions using trusted computing technology are proposed.The seal and sign features are applied in the schemes to ensure the safety of identity authentication.One scheme is based on DH algorithm and the other is based on IBE algorithm.
