An Improved Approach Towards the Model of Trust-X

Speeding up subsequent negotiations between the same negotiators is a problem worth of research in the area of trust negotiation. Based on the analysis of trust-X, this paper proposes an improved approach towards the model of trust-X. The improved model introduces the concept of visiting card to identify every entity in an open system, and records the credentials that the counterpart disclosed during the previous trust negotiations in his history information base. Every negotiation is conducted without repeating disclosure credentials disclosed during previous negotiations. Meanwhile, the improved model encrypts the transmitting messages to keep the system away from eavesdropping or interception attack. The improved approach has a higher level of security. Meanwhile, it greatly speeds up subsequent negotiations between entities that interact with each other frequently.
