| 摘 要： | 分析了目前可信计算平台中的设计缺陷,提出了一种简单有效的物理攻击.该攻击能绕过完整性度量对可信计算平台进行攻击.针对这种物理攻击,提出了基于信号完整性分析的TPM(trusted platform module)芯片改进设计方案.在TPM中增加模拟参数度量子模块TPM-APM(TPM-analog parameter measurement),TP-APM子模块通过对可信硬件平台特定网络的模拟参数进行度量与验证,进而保证整个可信硬件平台系统的完整性. |
| 关 键 词： | 可信计算 TPM 物理攻击 信号完整性分析 |

| Abstract: | By analyzing the design deficiency of current Trusted Computing platform,a simple and effective physical attack which can bypass the integrity measurement of Trusted Computing platform was presented.Facing this physical attack,a novel design method for TPM(trusted platform module) chip based on signal integrity analysis was proposed which could enforce the Trusted Computing Platform's credibility greatly.A sub-module called TPM-APM(TPM-analog parameter measurement)was implanted to the current TPM module.The... |
