Evolutionary Game Analysis of Security Information Sharing in Virtual Enterprise

Virtual enterprises take advantage of Internet technology to share information in order to win more market opportunities, thus it is critical to ensure the security of the process of information sharing, and security information sharing can effectively enhance the safety level of VE. We analyze the security information sharing of VE based on Evolutionary Game Theory, sets up the security information sharing model by the payoff matrix and analyze the evolutionary game in three kinds of situations by using Replicator Dynamics. The result reveals that sharing cost, income, potential loss and spillovers are the keys for information security sharing in VE.
