METHODS AND ARCHITECTURES FOR SECURE RANGING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18482069 titled 'METHODS AND ARCHITECTURES FOR SECURE RANGING

Simplified Explanation

A secure ranging system is described in this patent application. The system uses a secure processing system to deliver ranging keys to a ranging radio on a device. The ranging radio can then derive ranging codes locally based on these keys. A deterministic random number generator is used to derive the ranging codes using the ranging key and session parameters. Each device can independently derive the ranging codes and use them in ranging operations.

• The patent describes a secure ranging system that enables devices to derive ranging codes locally.
• The system uses a secure processing system to deliver ranging keys to the ranging radio on a device.
• A deterministic random number generator is used to derive the ranging codes using the ranging key and session parameters.
• Each device can independently derive the ranging codes and use them contemporaneously in ranging operations.

Potential applications of this technology:

• Secure ranging systems can be used in various wireless communication devices, such as cellular telephones and other devices.
• This technology can be applied in location-based services, where accurate ranging is crucial for determining the position of a device.
• It can also be used in wireless communication networks to improve the accuracy and security of ranging operations.

Problems solved by this technology:

• This technology solves the problem of securely delivering ranging keys to devices.
• It enables devices to derive ranging codes locally, eliminating the need for centralized processing.
• The use of a deterministic random number generator ensures consistent and secure generation of ranging codes.

Benefits of this technology:

• The secure ranging system provides enhanced security for ranging operations.
• Devices can independently derive ranging codes, improving the efficiency and scalability of the system.
• The use of a deterministic random number generator ensures consistent and reliable generation of ranging codes.

Original Abstract Submitted

A secure ranging system can use a secure processing system to deliver one or more ranging keys to a ranging radio on a device, and the ranging radio can derive locally at the system ranging codes based on the ranging keys. A deterministic random number generator can derive the ranging codes using the ranging key and one or more session parameters, and each device (e.g. a cellular telephone and another device) can independently derive the ranging codes and derive them contemporaneously with their use in ranging operations.
