A non-interactive optimistic fair exchange e-commerce protocol model based on the publicly verifiable secret sharing is presented. The main idea of our exchange protocol is to interchange verifiable and recoverable keys of the symmetric encryption for participants＇ items. So it is especially suitable for exchange of large-size items. Furthermore, our protocol is efficient and simple as it does not need interactive proof system which has been adopted by a large quantity of previously proposed fair exchange protocols. Based on a modified （2,2） secret sharing scheme, a concrete non-interactive fair exchange e-commerce protocol is designed.展开更多

The competitive attitude of the member states of the EU （European Union）, to become the most attractive for companies results in law reforms aiming at more flexible conflict between shareholders. Besides, the economic objective of avoiding a company＇s dissolution, the English, Dutch, and Belgian exit proceedings for the settlement of disputes between shareholders set up a social objective： protecting the interests of the minority shareholder of a private limited company. The paper consists of four chapters. The introduction lays out the necessity of buy-outs for shareholders of a private limited company. The first chapter describes the different facts justifying the buy-out of a shareholder on the basis of serious grounds. The second chapter presents the findings of a comparative research of the valuation of the shares transferred in an English, Dutch, and Belgian procedure. Finally, the conclusion summarises in which way the English, Dutch, and Belgian legal system protect the interests of the minority shareholder of a private limited company.展开更多

In the period of deepening the reform, the idea of sharing means a new stage of shared development aimed at the goal of common prosperity. It is of great guiding significance for promoting the healthy development of economy and society, building a well-off society in an all-round way and realizing the Chinese dream.展开更多
