Policy embedded dynamic integrity active measurement architecture

In order to improve the current integrity measurement methods in activity,flexibility and efficiency,this paper presented a TPM-based architecture PEDIAMA(policy embedded dynamic integrity active measurement architecture).It embedded measurement policies into measurement targets,thus no extra memory was needed to hold and maintain the policies,and the cost in searching and maintaining was very low,so increased the efficiency of the whole system.As the policies were flexible in contents and easy to access,not only the external measurement requests could be fulfilled instantly,but also the embedded policies could be performed actively.For the architecture and the measurement process were protected by TPM,also protected the policies and some measurement results by digit signature,boosted the security of the whole system.Experimental results show that,PEDIAMA can instantly detect the attack aiming at running objects with lower overhead.
