Research On Security For Palm Electric Power Business Hall Based On NFC Technology

With the rapid development of modern communication technology,mobile phone has been a necessity for people,all kinds of mobile phone terminal have become an essential part of life,people can stay at home to complete a variety of payment and payment in the sale of a variety of mobile phone terminal.In view of the actual demand,the power companies also actively explore a new model of mobile phone mobile service market,the traditional business is shifted to the mobile phone client,to meet the users of the business needs.With the palm power business hall launched mobile payment has been paid more and more attention,so the security of payment has become the focus of user.In this thesis according to the demand of mobile payment for electric power company,a payment method based on NFC(Near Field Communication)technology is put forward.The encryption algorithm of 3DES(Data Encryption Standard)and ECC(Elliptic Curves Cryptography)is used to ensure the security of the system.NFC technology by RFID technology evolved,but it is different from the RFID technology,it can solve the communication problem between the mobile terminal and the receiving terminal,and can be simulated with NFC chip mobile phone into non-contact identification card to communicate with POS in order to complete the payment.By understanding the relationship between NFC technology and near field payment,the security of the near field payment function based on the NFC technology has become the research focus in this thesis.The following aspects of the work have been done according to the customer needs:The security of the NFC technology is analyzed in the near-field payment system.The relationship between NFC technology and near-field payment is clarified,and the overall security principle of the system are summarized.The ECC encryption algorithm,RSA encryption algorithm and 3DES encryption algorithm are analyzed.The speed of the ECC algorithm is faster than the RSA algorithm encryption and it is more suitable for short data encryption.The speed of 3DES encryption algorithm is faster than the ECC encryption algorithm and it is more suitable for large data encryption.According to the above analysis,a hybrid encryption algorithm of ECC encryption algorithm and 3DES encryption algorithm is put forward,which is more suitable for the near field payment.It can increase the security of the key and to ensure confidentiality of the transmission of the transaction.The security of applying this algorithm to the system is verified by experiments.The results show the effectiveness of the proposed algorithm.
