SECURE COMMUNICATION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18164131 titled 'SECURE COMMUNICATION METHOD AND APPARATUS
Simplified Explanation
The abstract describes a secure communication method and apparatus for ensuring the security of direct communication between terminal devices. Here is a simplified explanation of the abstract:
- The method involves a first terminal device receiving a key generation parameter from a first network element. This parameter includes a temporary identity of the first terminal device.
- The first terminal device generates a discovery key based on the key generation parameter.
- The first terminal device sends a ProSe request message to the second terminal device. This message includes the temporary identity and a message integrity code generated using the discovery key.
- The second terminal device receives the ProSe request message and verifies the first terminal device based on the message integrity code. This ensures the security of the direct communication between the two terminal devices.
Potential applications of this technology:
- Secure communication between mobile devices: This method can be used to establish secure direct communication between mobile devices, ensuring the privacy and integrity of the transmitted data.
- Proximity-based services: The method can be applied in proximity-based services, where devices need to securely communicate with each other in close proximity, such as in Internet of Things (IoT) applications or peer-to-peer file sharing.
Problems solved by this technology:
- Ensuring secure direct communication: The method addresses the need for a secure communication method between terminal devices, protecting against unauthorized access or tampering of data during transmission.
- Authentication and verification: By using a temporary identity and message integrity code, the method provides a way to authenticate and verify the participating devices, ensuring that only trusted devices can establish direct communication.
Benefits of this technology:
- Enhanced security: The method provides a secure communication channel between terminal devices, protecting against eavesdropping, data manipulation, and unauthorized access.
- Simplified setup: The use of key generation parameters and message integrity codes simplifies the setup process for establishing secure direct communication between devices.
- Efficient communication: By directly communicating between terminal devices, the method eliminates the need for relaying data through intermediate network elements, resulting in faster and more efficient communication.
Original Abstract Submitted
A secure communication method and apparatus are disclosed, to ensure security of a direct communication between terminal devices. In this application, a first terminal device may receive a key generation parameter from a first network element, where the key generation parameter includes a ProSe temporary identity of the first terminal device. Then, the first terminal device may generate a first discovery key based on the key generation parameter. The first terminal device sends a ProSe request message, where the ProSe request message includes the ProSe temporary identity and a message integrity code, and the message integrity code is generated based on the discovery key. The second terminal device receives the ProSe request message, and verifies the first terminal device based on the message integrity code, to ensure the security of a direct communication between the first terminal device and the second terminal device.
