Mobile downloading data transmission method with privacy protecting function

Abstract

The invention discloses a mobile downloading data transmission method with a privacy protecting function. A credible agent node is introduced by the method, and after being encrypted by the agent node, data is distributed to a transfer node, so that the transfer node is prevented from learning the address of user request content, meanwhile; a data packet can be enabled to be distributed to the transfer node in a low-overhead way by using a privacy protection content distribution algorithm, so that privacy is not leaked to a third part in a wireless transmission process, and the reliability of data transmission on a wireless channel is not damaged. According to the method provided by the invention, private information, such as personal browsing record and request content, is enabled not to be leaked to the third part while the internet network data transmission rate can be effectively improved for a mobile user; meanwhile, in consideration of limitation of a mobile terminal resource and the dynamic nature of a wireless network, while a privacy protection mechanism is introduced, the influence on the data transmission efficiency is reduced as soon as possible, and safe and reliable transmission of the data is guaranteed in a low-overhead way.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a mobile offloading data transmission method with a privacy protection function. Background technique [0002] The increasing popularity of smart phones and tablet computers enables users to experience ubiquitous Internet access and rich applications (APPs) through mobile operator network services. These mobile apps include video streaming apps, photo sharing apps, cloud storage services, etc. Among them, video applications are particularly popular among users, winning a large number of user groups for current content service providers, and making mobile video traffic gradually become the mainstream. In order to attract more users and improve user experience, content service providers often provide high-definition video. However, high-definition video requires a higher network data transmission rate to ensure user experience, which brings great challenges...
