Problems solved by technology

As long as there is a slight change in the standard, the hardware must be continuously redesigned to meet the requirements. In addition to being time-consuming and laborious, it is also inefficient. Therefore, it is necessary to seek a hardware configuration that can improve the repeated design when the standard has not yet been determined.

Embodiment Construction

[0019] Referring to Fig. 2, this figure is a configuration diagram of the present invention. The spirit of the present invention is to provide an interface device 2 that utilizes a storage body to record changes of variable field fields. When the standard changes, as long as the information in the memory is updated, the data signal 1 is also processed by the interface device 2 and then sent to the CCM control logic 3 to achieve the purpose of the standard change field, and there is no need to modify the CCM control logic 3, especially the output The input interface part can greatly save the time and effort of hardware design.

[0020] Please refer to FIG. 3 , which is a specific embodiment of the present invention. In this embodiment, the invention includes:

[0021] A first storage unit 20 stores at least one item of auxiliary information, and when the encryption standard changes, the auxiliary information stored in the first storage unit 20 is updated externally.

Abstract

This invention discloses a kind of programmable controlled data processing apparatus by using a storing unit to store the mutable fields with WLAN encryption standard. When the encryption standard varies, it only needs to modify this storing unit and decrease the modification of other parts. The data processing apparatus comprises: first storing unit, which stores at least one assistant information, if the encryption standard changed, it updates the assistant information in the first storing unit; a reading unit, which coupled with the storing unit, receives an index, gets the corresponding assistant information from the first storing unit according to this index; a processing unit, which coupled with the reading unit, receives the assistant information and a data signal, and processes the data signal according to the assistant information, and outputs a processing signal.

Description

technical field [0001] The invention relates to a programmable control data processing device, in particular to a programmable control data processing device which can reduce the range of hardware modification when the encryption standard of a wireless local area network (wireless LAN, WLAN) is changed. Background technique [0002] In recent years, with the advancement of wireless communication technology, various digital mobile products such as mobile phones, notebook computers, and PDAs have realized the desire of human beings for wireless communication. In addition to getting rid of the shackles of traditional wired phones, users are more free and also Bring people closer together. [0003] However, the wireless network transmits in space by means of broadcast. In other words, as long as they are willing, anyone can capture the transmission signal in the space, know the transmission content, and then engage in counterfeiting, tampering and other attacks that endanger ne...
