Root trust transfers in turn to BIOS (Basic Input Output System), OS (Operating System) and eventually applications from TPM (Trust Platform Module) in Trusted Computing. Before every transfer of trust, integrity measurement module measures the integrity property of receiver and produces stored measurement log. A dynamic integrity measurement model is proposed to measure integrity during execution of computing platform. This model measures instruction code of operating system and user processes in memory to construct stored measurement log at the time of system call or process scheduler. A prototype is realized under Linux to analyze the validity and performance of this model. Compared with other analogous model, this model can dynamically measure vivid integrity and detect attack during execution of computing platform with little performance cost.
