A Method of Network Coding to Ensure Public Network Security
Zihe Liang · Journal of Physics Conference Series · 2019
Abstract When connecting to the wireless network in public places, users’ personal information will be exposed in the public network, which is easy to be stolen and tampered with by third parties. In this paper, the author proposes a method to protect user information when connecting to public wireless networks in order to protect users’ privacy. Random linear network coding is used to encrypt the accessed user serial number, which is then forwarded to the upper layer. When transmitted to a specific node, the encrypted information is transmitted to the server for information decryption. After decoding the user serial number, the node is accessed. In this way, we can encrypt user information, reduce the delay time of forwarding, and improve the transmission efficiency. The time complexity is O(n2).
