Abstract: Plenty of security problems may occur when servers adopt Agent to deploy mobile codes so as to realize interactive storage between different business clients. In order to pursue a higher reliability of the software, and to make sure those Agents healthily running in an untrusted complex environment, after analyzing traditional integrity validating mechanism, combining I&A, PCC and reflection techniques, a new classified mechanism of enabling the integrity of trusted terminal Agents was proposed, and an efficient validating model with multiple interacting modules was designed, aiming at improving the reliability of the mobile codes by realizing its behaviors-monitoring.

Key words: software integrity protection, Proof-Carrying-Code (PCC), reflection, classified-protection, trusted software
