Patent Reveals Innovative Approach to Cyber Attack Detection in Mobile Communications

Strategic Insights -

A recent patent by NEC Corporation has proposed a groundbreaking solution to detect and prevent cyber attacks in mobile communication systems. The invention, filed by Yuichi Kusumoto on November 1, 2011, and published on August 25, 2015, aims to address the vulnerability of mobile terminals to cyber attacks by introducing a real-time detection system.

The proposed system includes a mobile terminal, a base station, an operation/maintenance server, and a gateway with a Deep Packet Inspection (DPI) function. If the base station detects an unusual amount of traffic from the mobile terminal, it transmits an alarm to the operation/maintenance server, which in turn activates the DPI function to inspect the traffic for potential cyber attacks. This proactive approach enables the base station to actively detect and prevent cyber attacks, even with large amounts of user data transmitted from the mobile terminal.

Key Takeaways:

  • The patent proposes a communication system that includes a mobile terminal, a base station, an operation/maintenance server, and a gateway with a DPI function to detect cyber attacks.
  • The system detects unusual traffic amounts from the mobile terminal and transmits an alarm to the operation/maintenance server, which activates the DPI function for real-time inspection.
  • The invention aims to address the vulnerability of mobile terminals to cyber attacks by providing a proactive detection system.
  • The proposed solution is designed to work in conjunction with the existing LTE (Long-Term Evolution) system and 3GPP (Third Generation Partnership Project) standards.
  • The patent has been assigned to NEC CORPORATION, with Yuichi Kusumoto as the inventor.

Statistics:

  • The patent was filed on November 1, 2011, and published online on August 25, 2015 (U.S. Patent Number 9119075).
  • The proposed system includes four key components: mobile terminal, base station, operation/maintenance server, and a gateway with DPI function.
  • The DPI function can detect cyber attacks in real-time, enabling proactive prevention of attacks.
