Abstract
Most current trust management systems cannot precisely reflect the dynamic feature of trust status. Based on the fundamental trust management principles and the thin client requirements in electronic commerce applications, by introducing the concept of Important Factor in trust calculation, a centralized trust management architecture and an efficient trust evaluation method were proposed. The trust evaluation method advocates defining as less formulae as possible to enable a simple and efficient trust evaluation system. And the parameters in trust evaluation equation can vary to adapt to different application environments. The simulation shows the new trust management model could precisely reflect the dynamic feature of trust status.
