Multicast Broadcast Service Keys - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187849 titled 'Multicast Broadcast Service Keys

Simplified Explanation

The abstract describes a patent application related to a user equipment (UE) joining a multicast broadcast service (MBS) session by sending a protocol data unit (PDU) modification request, generating and receiving encryption keys, and decrypting the received keys.

The patent application involves a user equipment (UE) sending a request to join a multicast broadcast service (MBS) session to a network function.
The UE generates a first key (K) for encryption purposes.
Upon receiving a PDU session modification complete message, the UE decrypts the encrypted second key (K) and key identification (KID) using the first key (K).

Potential Applications

This technology could be applied in:

Mobile networks for efficient multicast broadcast services.
Secure communication systems requiring key exchange protocols.

Problems Solved

This technology addresses:

Secure key exchange for joining multicast broadcast services.
Efficient encryption and decryption processes for network communication.

Benefits

The benefits of this technology include:

Enhanced security for multicast broadcast services.
Improved efficiency in key exchange processes.
Seamless integration with existing network functions.

Potential Commercial Applications

Potential commercial applications of this technology include:

Mobile network operators looking to enhance multicast services.
Communication system providers focusing on secure data transmission.

Possible Prior Art

One possible prior art could be related to existing key exchange protocols in network communication systems.

Unanswered Questions

How does this technology impact network latency?

This article does not address the potential impact of this technology on network latency. Implementing encryption and decryption processes could potentially introduce latency in network communication.

Are there any compatibility issues with existing network protocols?

The article does not mention any potential compatibility issues with existing network protocols. It would be important to consider how this technology integrates with and affects current network standards and protocols.

Original Abstract Submitted

a user equipment (ue) is configured to join a multicast broadcast service (mbs) session. the ue sends, to a network function, a protocol data unit (pdu) modification request comprising a request to join a multicast broadcast service (mbs) session, generates a first key (k), receives a pdu session modification complete message comprising an encrypted second key (k) and a key identification (kid) corresponding to the kand decrypts the kiss using the k.
