On the Energy Costs of Post-Quantum KEMs in TLS-based Low-Power Secure IoT

Recent achievements in designing quantum computers place a serious threat on the security of state-of-the-art public key cryptography and on all communication that relies on it. Meanwhile, security is seen as one of the most critical issues of low-power IoT devices even with pre-quantum public key cryptography since IoT devices have strict energy constraints and limited computational power. Thus, state-of-the-art dedicated hardware accelerators have been deployed to facilitate secure and confidential communication with well established protocols on such devices.
