Abstract—Certificateless Public Key Cryptography (CL-PKC) schemes are particularly robust against the leakage of secret information stored on a Trusted Third Party (TTP). These security features are particularly relevant for Internet of Things (IoT) domains, where the devices are typically pre-configured with secret keys, usually stored locally on the TTP for following maintenance tasks. Despite some contributions already proposed the adoption of CL-PKC schemes in constrained IoT devices, current solutions generally require high message overhead, are computationally demanding, and generally, place a high toll on the energy budget.
