METHOD AND APPARATUS FOR SUPPORTING SECURITY OF ADHOC GROUP CALL IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18324908 titled 'METHOD AND APPARATUS FOR SUPPORTING SECURITY OF ADHOC GROUP CALL IN WIRELESS COMMUNICATION SYSTEM

Simplified Explanation

The patent application is about a communication system that supports high data transmission rates in 5G or 6G networks.

  • The method involves a first terminal in a wireless communication system.
  • The first terminal generates an AGK (Adhoc Group Key) for an adhoc group.
  • The first terminal transmits a communication request message to the adhoc group, including a list of IDs of multiple second terminals connected to the first server.
  • The first terminal receives a communication return message signed by the first server.
  • The first terminal performs encryption and signing operations on the AGK using authentication information related to both the first terminal and the second terminals.
  • The first terminal transmits a security material request message for adhoc group communication, including the encrypted and signed AGK.
  • The first terminal receives a response message to the security material request, enabling secure communication within the adhoc group.


Original Abstract Submitted

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method of a first terminal in a wireless communication system is provided. The method comprising: generating an AGK for an adhoc group; transmitting an adhoc group communication request message including a list including IDs of a plurality of second terminals included in the adhoc group and connected to the first server; receiving an adhoc group communication return message signed by the first server; performing an encryption and signing operation on the AGK based on first authentication information related to the first terminal and the second authentication information; transmitting an adhoc group communication security material request message including the AGK that is encrypted and signed; receiving an adhoc group communication response message in response to transmitting the adhoc group communication security material request message; and performing a secure communication.
