Abstract

The invention discloses a method and system for access control of a wireless hotspot based on a dynamic key. The method includes: after the wireless hotspot is connected to a terminal, sending a first public key and a first private key to the terminal, and simultaneously The wireless hotspot stores the second private key and the second public key respectively corresponding to the first public key and the first private key; after the terminal is connected to the wireless hotspot, it does not receive the When the wireless hotspot sends the first public key and the first private key, the terminal disconnects from the wireless hotspot; after receiving the terminal disconnection instruction, the wireless hotspot sends the terminal a command to obtain the access password and MAC address. Request; the wireless hotspot receives the access password and MAC address sent by the terminal, and matches the access password and MAC address with the access password and MAC address in the preset database, and judges whether the terminal is allowed to access through the matching result network. It solves the security of data transmission in the internal information system of the LAN.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for access control of a wireless hotspot based on a dynamic key. Background technique [0002] Today, informatization, networking, and automation are constantly integrated into the office system. The establishment of a local area network has become an inevitable choice for a unit to improve office efficiency. It is an important part of internal construction, and it is also a direct way for internal employees to obtain resources and update information in a timely manner. , and the popularization and application of wireless network technology has built the entire enterprise as an office platform. Whether it is in the office, in the production workshop, warehouse, or outdoor open space, it can intervene in the network anytime and anywhere to realize the connection with the intranet and the Internet. Due to the limitations of traditional wired LAN, ...
