điều này không chỉ làm giảm nguy cơ của một hành vi vi phạm an ninh giữa các đại lý, nó cũng giúp để đảm bảo các hoạt động công bằng và không thoái thác giao dịch kết luận. Điều này giúp tăng sự tin tưởng rằng các bên sẽ có trên thị trường, | Security Trust and Privacy such incidents buyer and seller agents within the marketplace should not be allowed to negotiate with each other directly. By introducing an intermediary to control and monitor negotiations this not only reduces the risk of a security breach amongst agents it also helps to ensure fair practices and non-repudiation of concluded transactions. This helps to increase the trust that parties will have in the marketplace and it also reduces the possibility that each agent may access the private information of other agents. This means the private information is only available to the controller of the virtual marketplace and is carefully protected against illegal access. Secure Transport and Agent Integrity Due to the fact that this application is based on a mobile agent concept the agent and its data will be susceptible to attack while it transverses the network especially if this application is deployed over the Internet. Therefore a secure transport mechanism is required Guan Yang 1999 for example encryption of the agent before transportation. Agent integrity can also be achieved using a similar mechanism as discussed by Wang Guan and Chan 2001 . Trusted Client Applications Not only fellow agents but also the virtual marketplace itself has to be protected from malignant agents. To ensure that only trusted agents are allowed into the marketplace only agents manufactured from trusted agent factories Guan 2000 Guan Zhu 2001 Zhu Guan Yang 2000 are allowed into the server. In this particular implementation only agents constructed and verified by the provided client applications are granted access to the marketplace. The disadvantage of doing so is that this does not allow clients to custom build their own agents that might have greater intelligence and negotiation capabilities but this downside is seen as minimal since most users would not bother to go through the complexities to do so anyway.
