摘要
可信云计算是一种全新的互联网应用模式,它即将成为人们获取信息和服务的主要方式。但在云平台向用户提供远程证明方面,还存在明显的安全漏洞和不足之处。目前所使用的证明方法暴露了平台的属性信息,使攻击者跟踪这些信息进行有针对性的攻击。使用可信环签名的远程证明方法,可以保证平台的匿名性,保护了平台隐私,提高了平台的安全性。最后,通过IKE协议验证了可信环签名方法,确保了它在云计算平台上的可行性。
Trusted cloud computing is a new Internet application pattern,which will soon become the dominant mode to access services and information.But there are obvious security vulnerabilities and inadequacies as the cloud platform provides users with remote attestations,i.e.,the platform attribute information is exposed to attackers,so that they may trace those information to carry out directional attacks.The application of trusted ring signature remote attestation method can ensure the platform anonymity,protect its privacy and improve its security.Finally,by means of IKE protocol the trusted ring signature method is verified to ensure its feasibility on the cloud computing platform.
