Abstract

The invention provides a data package segmented encryption and transmission processing method and device. The data package segmented encryption and transmission processing method comprises a step of carrying out data package transmission processing on a medium access control layer: at first, carrying out segment preprocessing on a data package according to data package configuration information and a segment threshold value; then configuring desired control data for a first segment in an encrypted manner before sending the first segment; when the pre-set processing of sending each segment is executed, encrypting the current segment, and sending the previous segment and configuring the control data needed by encrypting the next segment simultaneously; and repeatedly executing the above steps so as to send the single segmented one by one, so that the entire data package is encrypted, transmitted and processed in a segmented manner. With the adoption of the data package segmented encryption and transmission processing method and device provided by the invention, the storage space and the time of transmitting and processing the data package can be saved, and the efficient transmission processing of sending the data package in the segmented manner can be ensured.

Description

technical field [0001] The invention relates to the field of network data transmission processing, in particular to a method and device for segmented encryption transmission processing of data packets. Background technique [0002] Wireless Local Area Networks (WLAN) is a very convenient data transmission system. Wireless local area networks use wireless communication technology to interconnect computer equipment to form a network system that can communicate with each other and realize resource sharing. [0003] 802.11 is a wireless local area network standard initially formulated by the Institute of Electrical and Electronics Engineers (IEEE). It is mainly used to solve wireless access between users and user terminals in office LANs and campus networks. The business is mainly limited to data access. [0004] An 802.11 WLAN is built on a cellular structure, which is subdivided into cells. Each cell (known in 802.11 terminology as a basic service set or basic service set (B...
