An agent-based multi rounds online auction protocol with sealed bids

Software agent technology is starting to create a series of new possibilities for the area of electronic commerce over Internet. In this paper, we intend to apply software agent technology along with cryptographic technology to automate and secure online auction over Internet. Furthermore, we proposed a novel implementing protocol for agent-based secure multi-rounds online auction with sealed bits, which not only retains the agent´s mobility and flexibility, but also takes secure measures to prevent the attacks from malicious bidders.
