WebHellman (ECDH) for establishing the 128-bit shared symmetric key for MAP. For instance, when using the secp256r1 curve, executing ECDH key exchange on the dedicated peripheral before starting the MAP protocol adds 1457 µJto the security energy budget needed. Undoubtedly, this is a significant increase, and somewhat justifies WebOpenShift 4. OpenShift 4 has been built with Go 1.12 since version 4.2 and thus supports TLS 1.3 in most components. Before Openshift 4.6, the router used HAProxy and OpenSSL from RHEL7 does not yet support TLS 1.3. In later versions, the router is based on RHEL and does support TLS 1.3.
