Abstract :
For the user packet data transmission security and privacy issues in xGSN of mobile communication network, we propose a "dynamic tunnel" defense mechanism based on GTP protocol. The method dynamically changes the Tunnel Endpoint Identifier (TEID) used for the transmission of user packets between SGSN and GGSN by building a mimicry gateway, which breaks the static correspondence between TEID and user identification, thus achieving the purpose of protecting user packet data. Theoretical analysis and simulation results indicate that the "dynamic tunnel" method can improve system security and effectively protect user privacy information with low communication overhead and latency.
