<p>According to the present invention, provided is a mobile POS terminal which includes: a wireless communications unit which performs wireless communications with an authentication server; a memory which stores a payment program for opening a POS terminal; a control unit which generates a first random number if the payment program is executed; and an identification module which, after generating a second random number, generates a first cryptograph and a first message authentication code using at least one among the first random number and the second random number and completes the opening of the POS terminal by storing a chain store number if the chain store number is received from the authentication server. [Reference numerals] (10,200) Authentication server; (100) Mobile POS terminal; (S201) Execute a payment program; (S202) Already opened?; (S203`) Generate a first random number; (S204) Input an operator identification number and an operator name; (S205) First random number, operator identification number, and operator name; (S206) Generate a second random number; (S207) Generate a first session key; (S208) Generate a first cryptograph; (S209) Generate a first message authentication code; (S210) First cryptograph, first message authentication code, and unique factor of an identification module; (S211) First cryptograph, first message authentication code, unique factor of the identification module, operator identification number, and operator name; (S212) Generate a second session key; (S213) Generate a second cryptograph; (S214) First cryptograph = Second cryptograph?; (S215) Generate a second message authentication code; (S216) First message authentication code = Second message authentication code?; (S217) Authenticate a terminal?; (S218) Authenticate an operator?; (S219,S220) Chain store number and terminal serial number; (S221) Store the chain store number and terminal serial number</p> |
