Embodiment Construction

[0030] The core idea of ​​the present invention is that the wireless local area network terminal encrypts the user certificate locally by using the user password and stores it in an external memory connected to the wireless local area network terminal; when the user certificate needs to be used, the wireless local area network terminal extracts the locally encrypted user certificate from the external memory certificate, and decrypt it with the user password to obtain the user certificate.

[0031] In addition, after the user certificate is updated, the updated user certificate is locally encrypted using the user password, and when the external storage device is connected to the wireless local area network terminal, the locally encrypted updated user certificate is stored in the external storage device.

[0032] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0033] figure 1 It is a flowchart of the managem...

Abstract

The invention discloses a user certificate management and a use method and a mobile terminal thereof. The method comprises the following steps: the mobile terminal uses a user code to locally encrypt and store the user certificate; and when the user certificate is needed, the mobile terminal extracts the user certificate with local encryption and decrypts the user certificate with the user code, thus obtaining the user certificate. The method and the mobile terminal can realize the loading of the user certificate in the mobile terminal which is not provided with an SIM card slot, thus not only extending the application scope of WAPI, but also adding no operation difficulty and improving the portability. In addition, the stored user certificate in the external storage is locally encrypted for one time, thus being safer than the user certificate which uses an SIM card as the storage medium and is not encrypted. Particularly, when the storage mediums (such as external storage and SIM card) which store the user certificate are lost, the safety advantage of the local encrypting memory is much more obvious.

Description

technical field [0001] The invention relates to the field of wireless local area networks, in particular to a management and use method and a mobile terminal of a wireless local area network authentication and security infrastructure user certificate. Background technique [0002] The emergence of wireless local area networks (Wireless Local Area Networks, WLAN for short) is more and more widely used in enterprises and homes because of its portable and flexible features. The requirements for information security caused by this have become the key direction of wireless local area network development. Change. [0003] WAPI is composed of WAI (WLAN Authentication Infrastructure, wireless local area network authentication infrastructure) and WPI (WLAN Privacy Infrastructure, wireless local area network privacy infrastructure), and the security mechanism realizes functions such as authentication of user identity and encryption of transmitted data. WAI is responsible for authent...
