Abstract

The blistering development of both worldwide Internet of Things (IoT) networkshas heightened the necessity of effective and forward-looking identity protection. The oldidentity techniques which are based on RSA and ECC are unsafe since quantum computerswill crack them. In order to deal with this issue, the present paper will propose a quantumresistant identity management protocol, Quantum-Resistant Global IoT Identity Protocol, QRG-IoTIP, which is resistant to quantum attacks as well. The suggested system involves a mixture of PUF-based hardware identities, post-quantum cryptography (PQC), blockchainbased decentralized identity and zero-knowledge proof to provide secure and private authentication of devices. It is also compatible with the complete lifecycle of identity, such as onboarding of the device, key generation, authentication, sharing of trust, revocation and key rotation. Experimental evidence indicates that QRG-IoTIP is much more efficient in terms of authentication time and energy consumption, as well as, in terms of memory consumption and scalability, and secure than the current PQC-based identity schemes. All in all, the proposed system will provide an efficient and future-enabled identity solution to large-scale global IoT settings.
