面向多类型节点的混合多级μTESLA协议
Hybrid multi-level μTESLA protocol for multi-type nodes
摘要
Abstract
With the widespread applications of 5G technology and the forward-looking researches on 6G network technology,IoT devices have been extensively used in various practical scenarios,leading to an increasingly complex wireless communication network.In such a complex wireless communication environment,ensuring data security and communication efficiency has become particularly crucial.Broadcast authentication protocols,as one of the main solutions,have been applied in multiple scenarios.However,when facing secure broadcasts to multi-type and large-scale nodes,existing protocols still have limitations.To address this issue,an innovative broadcast authentication protocol is proposed,named the hybrid multi-level TESLA protocol.This protocol integrates and optimizes the advantages of the existing µTESLA protocol and its variants,with innovative improvements specifically for environments with multiple types of nodes.The protocol employs a dual-layer key chain design,where the high-level key chain has longer time intervals for generating and managing the low-level key chains;the low-level key chains are directly used for message authentication.This design not only enhances authentication efficiency but also significantly reduces the burden on broadcast nodes in terms of key usage and storage.Moreover,the low-level key chains are divided into multiple groups,each dedicated to broadcasting messages to a specific type of node group,achieving classified broadcasting and dynamic optimization of resources for different types of node groups.关键词
