To improve the performance and network security of collaborative commerce chain system and to deal with shortcomings of existing solution to electronic commerce, Mobile Agent technology was introduced into the modeling of network--based collaborative commerce chain system. Based on Mobile Agent properties, problems of security and network security confronted with Mobile Agent in the transaction process of network--based collaborative commerce chain were analyzed. Finally, a prototype system between the customer Agent and the supplier Agent was used to expatiate security negotiation bargain procedure based on Mobile Agent under the public key infrastructure and certification authority.
