Embodiment Construction

[0056] see figure 1 , figure 1 It is a schematic diagram of a communication system provided by an embodiment of the present invention, and the communication system includes an access point AP and stations in a Basic Service Set (Basic Service Set, BSS) served by the AP.

[0057] The IEEE802.11 specification stipulates the physical layer and MAC layer protocols for wireless transmission on the 2.4GHz, 5GHz or even 60GHz frequency spectrum. In a basic service set BSS stipulated in the IEEE802.11 specification, an AP is a station in a BSS that assumes the function of a control entity, and provides access to a distribution system (Distribution System, DS) for other stations associated with it. In addition, the AP can also use a point coordination function (Point Control Function, PCF) to coordinate the data transmission of each station. The APs in the communication system in this embodiment are associated with 5 stations from 1 to 5.

Abstract

Disclosed are a method for allocating an addressing identifier, an access point, a station and a communication system. The method for allocating an addressing identifier comprises: notifying, by an access point, at least two stations of encrypted new MAC addresses corresponding to each station, and instructing a pre-determined change condition, so that the at least two stations respectively change respective MAC addresses into respective new MAC addresses when reaching the pre-determined change condition; and when the pre-determined change condition is reached, updating, by the access point, the MAC addresses of the at least two stations into new MAC addresses corresponding to the stations, so that the new MAC addresses are used as the MAC addresses of the stations when messages are received from the stations or sent to the stations subsequently. By means of the method above, the present invention prevents an eavesdropper tracking a terminal through the MAC addresses so as to acquire the privacy of a user, thereby guaranteeing the privacy security of the user.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for allocating addressing identifiers, an access point, a station and a communication system. Background technique [0002] A wireless local area network (wireless local area network, WLAN) can provide wireless data transmission services for terminals within a limited range. In an IEEE802.11-based WLAN (also known as Wi-Fi, Wireless Fidelity, wireless fidelity), devices such as a gateway can also enable terminal devices therein to access the Internet (Internet). Due to the advantages of fast deployment, convenient use and high transmission rate, Wi-Fi has been widely used in various industries. [0003] The IEEE802.11 standard stipulates that addressing in a WLAN is based on a Media Access Control (Media Access Control, MAC) address. Usually, an eavesdropper can obtain the MAC address of the wireless message sender and receiver by receiving and analyzing message packets on th...
