COPS: a model and infrastructure for secure and fair electronic markets

摘要

Open electronic markets on the Internet have many advantages compared to traditional markets. A variety of new business models, types of markets and digital products emerge, because they potentially generate revenues. In order to support the realization of secure and fair electronic markets, it is important to address the security risks without lowering the advantages of the Internet. In this work, we describe a model for secure and fair markets, which supports this integrated approach. It considers security and fairness of market transactions, different market forms, digital goods and the impact of different business models. Based on our market model, we developed the COPS infrastructure that provides a framework for designing market transactions, an execution environment for market transactions, different (trusted and non-trusted) services and appropriate security mechanisms to realize secure and fair electronic markets.
