Title:
The encryption method and bank point-of-sales of communication with bank point-of-sales and a mobile terminal
Document Type and Number:
Japanese Patent JP6279765
Kind Code:
B2
Abstract:
Disclosed is an encryption method for communication between a financial POS and a mobile terminal. The encryption method for communication comprises the steps: the financial POS and the mobile terminal generate a common temporary key Kmaster, the mobile terminal sends a Bluetooth address BD_ADDR to the financial POS, and the mobile terminal and the financial POS separately add the temporary key Kmaster and the Bluetooth address BD_ADDR of the mobile terminal into a key generation formula to generate an encryption key Kcipher; and the financial POS or the mobile terminal performs an exclusive OR operation on a plaintext data stream to be sent and the encryption key to generate an encrypted transmission ciphertext. The encryption method of the present invention enables data to be transmitted securely, provides a simple algorithm and occupies fewer software and hardware resources, thereby effectively ensuring a communication rate between the financial POS and the mobile terminal.
