Many low-functionality devices lack sufficient protection, yet they transmit sensitive private data. Addressing limited computation, small storage, and low power consumption requires lightweight security mechanisms. This paper designs a lightweight IoT security system and evaluates its overall power consumption and latency. Results show MQTT message protection with 0.3 s latency and 1.683 mJ power consumption.","cbCaijGa98j0pEiQ","https://ap.wps.com/l/cbCaijGa98j0pEiQ","pdf",491343,1,5,"English","en","# Introduction\n# IoT Security Challenges\n## Scalability\n## Heterogeneity","[{\"question\":\"Why does IoT security risk increase as more devices connect?\",\"answer\":\"As the number of IoT devices grows, the security and privacy risks also increase, especially when many devices transmit sensitive data without adequate protection.\"},{\"question\":\"What constraints motivate a lightweight IoT security approach?\",\"answer\":\"IoT platforms must handle low computation power, small data storage, and low power consumption, which make traditional security approaches too heavy.\"},{\"question\":\"What performance did the lightweight system achieve for MQTT message protection?\",\"answer\":\"The lightweight security system secured MQTT messages with a latency of 0.3 seconds and power consumption of 1.683 mJ.\"}]",1780088475,13,{"code":4,"msg":28,"data":29},"ok",{"site_id":30,"language":22,"slug":31,"title":13,"keywords":32,"description":14,"schema_data":33,"social_meta":84,"head_meta":86,"extra_data":88,"updated_unix":25},105,"development-of-a-lightweight-iot-security-system","",{"@graph":34,"@context":83},[35,52,66],{"@type":36,"itemListElement":37},"BreadcrumbList",[38,42,46,49],{"item":39,"name":40,"@type":41,"position":19},"https://docshare.wps.com","Home","ListItem",{"item":43,"name":44,"@type":41,"position":45},"https://docshare.wps.com/document/","Document",2,{"item":47,"name":12,"@type":41,"position":48},"https://docshare.wps.com/document/technology/",3,{"item":50,"name":13,"@type":41,"position":51},"https://docshare.wps.com/document/development-of-a-lightweight-iot-security-system/31750/",4,{"url":50,"name":13,"@type":53,"author":54,"headline":13,"publisher":56,"fileFormat":59,"description":14,"dateModified":60,"datePublished":60,"encodingFormat":59,"isAccessibleForFree":61,"interactionStatistic":62},"DigitalDocument",{"name":9,"@type":55},"Person",{"url":39,"name":57,"@type":58},"DocShare","Organization","application/pdf","2026-05-29",true,{"@type":63,"interactionType":64,"userInteractionCount":4},"InteractionCounter",{"@type":65},"ViewAction",{"@type":67,"mainEntity":68},"FAQPage",[69,75,79],{"name":70,"@type":71,"acceptedAnswer":72},"Why does IoT security risk increase as more devices connect?","Question",{"text":73,"@type":74},"As the number of IoT devices grows, the security and privacy risks also increase, especially when many devices transmit sensitive data without adequate protection.","Answer",{"name":76,"@type":71,"acceptedAnswer":77},"What constraints motivate a lightweight IoT security approach?",{"text":78,"@type":74},"IoT platforms must handle low computation power, small data storage, and low power consumption, which make traditional security approaches too heavy.",{"name":80,"@type":71,"acceptedAnswer":81},"What performance did the lightweight system achieve for MQTT message protection?",{"text":82,"@type":74},"The lightweight security system secured MQTT messages with a latency of 0.3 seconds and power consumption of 1.683 mJ.","https://schema.org",{"og:url":50,"og:type":85,"og:title":13,"og:site_name":57,"og:description":14},"article",{"robots":87,"canonical":50},"index,follow",{"doc_id":7,"site_id":30}]
