Two-way authentication method based on short-range wireless communication technology

The invention discloses a two-way authentication method based on the short-range wireless communication technology. The two-way authentication method comprises the steps that: a user registers a platform of a service provider and shares a key in a wireless communication mode based on WTLS; the user reserves an electronic ticket in the wireless communication mode based on WTLS; the user pays the fees of the reserved electronic ticket on a mobile POS machine by a mobile device through NFC and obtains security information of the electronic ticket; and the user verifies the security information of the electronic ticket on a verifier by the mobile device through the NFC. The two-way authentication method disclosed by the invention is mainly used for solving the problems that the NFC payment suffers eavesdropping, message tampering, replay attack and man-in-the-middle attack and the like in the existing scene; since two-way offline authentication is adopted in the payment and the verification phases of the electronic ticket, the security of the entire electronic ticket system is higher, the confidentiality is strong, and the two-way authentication method is applied to scenes with higher security performance demands, such as air tickets, train tickets, etc.
