AI Technical Summary

Technical Problem

The configuration of a unique nonce for authenticated encryption with associated data (AEAD) security operations in IEEE 802.15.4z ranging is not adequately addressed, impacting security and accuracy in ultra-wideband communication.

Method used

A protection frame is generated using a nonce comprising identification information, a round index, and a block index, ensuring secure communication by configuring the nonce based on these indices, which can include slot indices and packet numbers, and optionally cycle indices, to simplify agreement between transmitter and receiver.

Benefits of technology

This approach enhances security operations and ensures accurate ranging measurements by providing a structured and secure method for configuring nonces in ultra-wideband communication.

Abstract

Exemplary embodiments of this disclosure relate to methods, apparatus, devices, and computer-readable storage media for communication. In some embodiments, a first protective frame to be transmitted in a slot within a first round belonging to a first block may be generated based on a block-based time structure or a hyperblock-based time structure, wherein the block-based time structure or the hyperblock-based time structure comprises a plurality of blocks, each block comprising a plurality of rounds, and each round comprising a plurality of slots, and the first protective frame is protected by a first nonce comprising identification information, a round index, and a block index associated with the first protective frame, wherein the round index is the index of the first round, and the block index is the index of the first block. In this way, security operations can be performed and the security of the communication can be ensured.
