Low Power Wide Area Networks (LPWANs) is a huge and very quickly growing market expected to reach over 1000 billion USD globally by 2027. Due to their relatively large ciphertext and signature sizes and the lack of Non-Interactive Key Exchange (NIKE) the currently selected PQC algorithms are unusable in many IoT systems using constrained radio networks. NIST and academia must work together to, if possible, standardize algorithms with smaller ciphertexts, smaller signatures, and with additional features such as NIKE.
