Research On Mutual Secure Authentication Method For Mobile NFC

With the continuous development and popularization of mobile phones and smart devices,more and more people want to be able to apply them to various daily scenes,such as access control,mobile payments and so on.The Near Field Communication(NFC),as a short,high-frequency wireless communication technology,happens to be able to solve such needs.Mobile phones and smart devices equipped with NFC technology can use its active and passive workmode to complete the contactless access control unlock,mobile payment and electronic tickets mentioned above.It is by virtue of short distance,and fast,NFC is applied to a variety of fields in a short period of time.However,when more and more people use this technology,the security and reliability of it have received an unprecedented attention.Because NFC communication is performed in an open and uncontrollable wireless environment,the data communication between devices and devices faces many security threats,including eavesdropping,message tampering,and cloning attacks,etc.It is because of the existence of these security threats,users have a great concern about the security of NFC technology,which hinders its further development and popularization.In terms of the security problem of NFC technology,this paper mainly studies the mobile NFC mutual security authentication method.Firstly,this paper introduces the NFC technology,including the working mode,working principle and performance comparison with other technologies.And then the contents of the NFC security authentication scheme are also introduced,including some information security technologies used in the authentication process,such as symmetrical encryption,asymmetric encryption,and hash functions.Secondly,according to the actual security requirements of NFC system and combined with plenty of previous research analyses,a new lightweight NFC security authentication scheme is put forward in this paper.The scheme uses the shift transform algorithm aimed at hiding the identity of both sides of the communication,and uses the confusion algorithm to realize the message encryption and decryption in the authentication process.At the same time,in order to prevent the synchronous attack,the scheme uses the cache backup method to achieve fast synchronization recovery.Compared with other existing schemes,theanalysis results show that while improving the functionality,the new scheme also has higher security and better performance.Finally,for those application fields where have higher demand for security,a security authentication scheme based on NTRU algorithm is designed in this paper.Combined with the characterisitics of NFC technology,this scheme uses an confusion algorithm,pseudo-random number function to transform the identify of communication both sides anonymously so that the scheme can meet the authentication requirements for higher security.At the same time,the use of hash function and random number helps the scheme defense against eavesdrop,forward attack and so on.Analysis shows that with a certain computation cost,this protocol can resist many security threats and attacks and improve the user experience also,and it is very suitable for some authentication fields that have a high degree of security requirements for the certification area.
