As the technology of mobile devices spreads fast,the price of mobile devices is getting *** of the people have mobile devices,and these devices have the technology of near field communication（NFC）.With the long time development and research,the mobile devices use NFC technology on the payment and authentication applications,and replace the smartcard,the access control card,and the credit card by using the card emulation *** helps the development of NFC *** recent years,more and more users begin using NFC technology on mobile payment and *** researches have proposed the related NFC authentication protocols,but their schemes are still lack of some security properties and functions,which are necessary for NFC authentication *** this paper,we propose a secure and efficient NFC authentication scheme between two NFC devices by the help of the authentication server that provides mutual authentication.

Investment strategy analysis of information system security in consideration of attackers

Journal of Southeast University(English Edition) 2017年第3期33卷 377-381页

In order to solve the problem of howa firm makes an optimal choice in developing information systems when faced with the following three modes: development by its own efforts, outsourcing them to a managed security service provider( MSSP) and cooperating with the MSSP, the firm 's optimal investment strategies are discussed by modeling and analyzing the maximum expected utility in the above cases under the condition that the firm plays games with an *** results showthat the best choice for a firm is determined by the reasonable range of the cooperative development coefficient and applicable conditions. When the cooperative development coefficient is large, it is more rational for the firm to cooperate with the MSSP to develop the information system. When the cooperative development coefficient is small, it is more rational for the firm to develop the information system by its own efforts. It also shows that the attacker's maximum expected utility increases with the increase in the attacker 's breach probability and cost coefficient when the cooperative development coefficient is small. On the contrary, it decreases when the cooperative development coefficient is large.
