Light-Weight Secure IoT Key Generator and Management

Abstract

Security is a critical element for IoT deployment that affects the adoption rate of IoT applications. This paper presents a Light-Weight Secure IoT Key Generator and Management Solution(LKGM) for industry automation and applications. Our solution uses minimum computing and memory resources that can be installed on half-credit-card-size embedded systems that enhances the securityof end-to-end communications for IoT nodes. A frequently changed randomly generated passphrase isused to authenticate each IoT node that is embedded with an encrypted unique authentication key. Fieldtest results were presented for an advanced manufacturing application that will only be activated whentwo authenticated IoT nodes are within the vicinity.
