Problems solved by technology

However, the NFC point-to-point technology does not verify the user's identity, and the user's identity is anonymous, which may cause attackers to use special equipment to carry out illegal access attacks, replay attacks, and man-in-the-middle attacks, bringing security risks and losses

Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0013] The invention proposes a near-field communication (NFC)-based wireless local area network (WLAN) authentication method. This access method uses two NFC modules: the user NFC module used by the user equipment and the NFC module of the WLAN; the two NFC modules work in a point-to-point mode. When the user requests to access the WLAN, the user's NFC module establishes NFC communication with the WLAN's NFC module, uses the Diffie-Hellman algorithm to exchange random information and calculates the symmetric key KEY; uses the public key cryptography certificate system authentication method, Verify user identity for symmetric key KEY signature and verification. The public key cryptographic certificate system used can use various algorithms, such as digital signature algorithm DSA, elliptic curve digital signature algorithm ECDSA and so on.

Abstract

The invention relates to a WLAN (wireless local area network) authentication method based on NFC (near field communication). According to the WLAN authentication method, two NFC modules working in a point-to-point mode are adopted, wherein the two NFC modules include a user NFC module of user equipment and an NFC module of a WLAN; when a user requests to access the WLAN, NFC communication between the NFC module of the user and the NFC module of the WLAN is established, and by the aid of the Diffie Hellman algorithm adopted by the user and the WLAN, random information is exchanged, and symmetric KEYs are computed; a public key certificate system authentication method is adopted to perform user authentication on signatures and verifications of the symmetric KEYs. The WLAN authentication method based on the NFC has the advantages that the NFC is protected from man-in-the-middle attack and replay attack, the WLAN is protected from illegal access attack to a certain extent, true and effectiveness of user identification are guaranteed, and safety in access to the WLAN by the NFC is enhanced.

Description

technical field [0001] The invention relates to a WLAN authentication method based on near-field communication (NFC). Background technique [0002] With the popularization of the network, the use of the wireless local area network (WLAN) is becoming more and more extensive. Currently, widely used WLAN authentication methods are based on the pre-shared key PSK. The complex pre-shared secret key PSK increases the difficulty of people's memory, so it is not uncommon to record passwords by handwriting and pass passwords manually. Due to people's poor security awareness, the way of transmitting the pre-shared secret key PSK is random, and the password setting is simple, and the password replacement is slow, resulting in great security risks. The tedious manual configuration of WLAN brings great inconvenience. [0003] NFC technology is a short-distance high-frequency wireless communication technology that allows point-to-point non-contact data transmission between electronic d...
