Secure Communication Method, Related Apparatus, and System - A simplified explanation of the abstract

This abstract first appeared for US patent application 18064501 titled 'Secure Communication Method, Related Apparatus, and System

Simplified Explanation

The abstract describes a secure communication method involving a security edge protection proxy (SEPP) device. Here are the key points:

  • The method involves a SEPP device at the transmitting end and an IP exchange service (IPX) device interconnected with the SEPP device.
  • The SEPP device obtains a message modification policy from the IPX device.
  • The SEPP device sends a first N32 message to the IPX device, which includes a first signaling message and the message modification policy.
  • The IPX device forwards the first N32 message to a SEPP device at the receiving end.
  • The SEPP device at the receiving end checks the first N32 message based on the message modification policy.

Potential applications of this technology:

  • Secure communication between different devices or systems.
  • Protection against unauthorized access or modification of messages.
  • Ensuring compliance with message modification policies.

Problems solved by this technology:

  • Ensures the integrity and security of transmitted messages.
  • Prevents unauthorized modifications or tampering of messages.
  • Provides a standardized method for checking messages based on predefined policies.

Benefits of this technology:

  • Enhanced security and privacy of communication.
  • Simplified implementation of message modification policies.
  • Efficient and reliable transmission of messages.


Original Abstract Submitted

A secure communication method includes a security edge protection proxy (SEPP) device at a transmitting end that obtains a message modification policy of an Internet Protocol (IP) exchange service (IPX) device interconnected with the SEPP device, and then sends a first N32 message to the IPX device, where the first N32 message carries a first signaling message and the message modification policy. The IPX device sends the received first N32 message to a SEPP device at a receiving end, and the SEPP device at the receiving end checks the first N32 message according to the message modification policy carried in the first N32 message.
