Design of Access Control Model for Big Data Information Leakage Risk Based on Evolutionary Game
The leakage of big data information will increase operational risk borne by network hosts,and in serious cases,lower level network terminals may be unable to access big data information servers.To solve the above problems,a big data information leakage risk access control model based on evolutionary game was designed.Based on the evolutionary game model,complete the evo-lutionary processing of big data information balance,solve the probability of information game,and derive the expression of the evolu-tionary game model,so as to improve the big data information fuzzy processing process based on the evolutionary game.Calculate the trust standard of big data information leakage behavior,refer to the information monitor setting conditions,and realize the assessment of big data information leakage risk.Aimed at the risk assessment results,complete the access evidence sampling of big data informa-tion,calculate the access control threshold,realize the control of information leakage risk access,and complete the big data informa-tion leakage risk access control model design based on the evolutionary game.Experimental results show that the big data information instantaneous leakage of the proposed method is always less than 2.3× 1011 MB,the operation risk borne by the network host is effec-tively controlled,and the lower level network terminal will not be unable to access the big data information server.
