A certificateless signature scheme with broadcastable updating on IoT
摘要
Abstract
Recent advancements in the Internet of Things(IoT)heighten the need for lightweight,secure au-thentication mechanisms.Current certificateless signature schemes exhibit considerable computational and communication overhead in dynamic environments where devices frequently join or leave the network,posing challenges for resource-constrained devices.This paper presents a certificateless signature scheme that incorpo-rates broadcast updates,effectively reducing the burdens associated with device updates.By integrating ellip-tic curve-based certificateless signatures with the Chinese Remainder Theorem and employing a broadcast mechanism for update messages,this scheme maintains constant communication overhead,significantly re-duces communication costs,and ensures low computational overhead.Experimental results indicate that the proposed scheme has reduced both computational and communication overhead compared with existing solu-tions when devices are updated,making it well-suited for IoT environments characterized by frequent device changes.Security analysis confirms that the scheme meets essential requirements,including anonymity,trace-ability,and non-repudiation,ensuring a robust security framework.关键词
