Problems solved by technology

Compared with the other two methods, the security of the scene where mobile devices are directly authenticated at close range to obtain permissions for other related operations (such as unlocking, accessing the LAN, etc.) in the point-to-point mode is particularly weak; and because only relying on ID As the basis for unlocking authentication, the diversity of its access process functions is also limited

Embodiment Construction

[0022] In order to make the purpose of the present invention, implementation scheme and advantages clearer, the specific implementation of the present invention will be described in further detail below, and the specific illustrations of the present invention can be found in figure 1 with figure 2 shown.

[0023] (1) When using two NFC devices to directly sense each other to authenticate the identity, because the authentication method only through the ID is too simple and the security cannot be guaranteed, a digital certificate issued by a trusted third-party authority CA is used instead of the ID for authentication. After the trusted authentication is established, access can be flexibly controlled by setting the relevant fields in the certificate to achieve multiple functional requirements. Down figure 1 It is a schematic diagram of the digital certificate structure issued by the CA center to the client device, listing the main parameters in the certificate.

Abstract

The invention provides an NFC (near field communication)-based point-to-point trusted authentication method. The method includes that a client NFC device generates an own key pair and sends an own public key, device information and personal identity information to a CA (certificate authority); after verifies the identity, the CA issues a certificate to the device, to be specific, the certificate is used for achieving identity authentication with an NFC server and accompanied with digital signing message of a publisher in a CA center; an access is provided for the digital certificate into the client NFC device, thus the device can perform the relative access through the certificate of its own; in case that the access to the NFC server for the identity authentication is required, the client NFC device transmits the own certificate to the NFC server through an established secret passage. According to the arrangement, the safe, reliable, flexible, convenient, resource-saving and multi-functional authentication is achieved during the NPC point-to-point transmission.

Description

technical field [0001] The invention relates to a trusted authentication method in a point-to-point mode. Background technique [0002] With the continuous development of wireless communication technology, NFC technology has been applied to various industries with its advantages of high transmission bandwidth and low energy consumption since its appearance. It can be said that as an extension of RFID technology, NFC breaks through the limitation that RFID can only realize information reading and judgment, emphasizing that both parties can exchange information at close range. The application in the NFC industry chain is mainly the payment industry and data transmission. Therefore, its security issues have gradually become a hot spot of concern. [0003] At present, the industry is generally optimistic about NFC technology. The most important thing is that the security of the card simulation mode and card reader mode of this technology has become mature, so it has gradually ...
