  text: Securing factory communication to protect corporate data is an important concern
    in the context of the Industrial Internet of Things (IIoT). Various cryptographic
    protocols can be used to establish secure communication channels. One of these
    protocols is the Transport Layer Security 1.3 (TLS 1.3) protocol. A key component
    of the TLS handshake protocol is the Elliptic Curve Diffie-Hellman Key Exchange
    (ECDHKE), a public key cryptosystem used to exchange keys over insecure channels
    which can be based on a number of standardized elliptic curves. A special form
    of elliptic curves are Montgomery curves which are advantageous compared to more
    traditional Weierstrass curves due to their fast arithmetic. This is especially
    important when the ECDHKE is performed on embedded devices and in time-critical
    situations. In this work, the performance of ECDHKE implementations using standardized
    Montgomery curves Curve25519 and Curve448 included in the wolfSSL library are
    evaluated on an embedded 32-bit STM32L476RG Nucleo development board designed
    by STMicroelectronics. The benchmark results show that using Curve25519 with around
    220ms for the key pair generation and the key agreement respectively is approximately
    75% faster than using Curve448 with around 900ms for each of the algorithms, which
    can be attributed to their differing security levels. These results suggest that
    the algorithms might not be fast enough for time critical situations.
