On security system: Study based on transaction chain
- 经济学院－会议论文 
Based on the division of transaction chain, we analyzed different security systems in different links by introducing reputation system and appeal system to the basic game model. It is proved that both reputation system and appeal system is able to lead the game to cooperative equilibrium. When both of them are in role, it allows a wider scope and is able to relax restrictions on assumptions that enable model works in each single system. Therefore, the two security systems on the transaction chain can complement each other and provide guarantees for online transactions together. 漏 2012 Springer-Verlag GmbH.
