In TLS 1.1 or lower, though, the use of ECDH_ECDSA or ECDH_RSA mandates that all signatures in the certificate chain must be ECDSA resp. RSA, which Mbed TLS doesn't check, and which therefore is an issue of non-compliance. However, as @sbutcher-arm stated, certificates still need to be correctly signed to be accepted, and hence the issue isn't significant from the perspective of security CC2642R: ECDH and ECDSA.

Observe ECDH being performed, with private keys of varying bit-length, after all of the measurements are done a plot will display, showing the dependency of ECDH duration on bit-length (if any), and the correlation of the two. This dependency cannot be directly connected to ECDSA, since a different algorithm might be used for scalar multiplication there (as we observed with one card), but can. Bug 1124827 - RFE: Enable ECDHE support in sendmailSummary: RFE: Enable ECDHE support in sendmail. *Sendmail* now supports ECDHE This update adds the Elliptic Curve Diffie-Hellman Ephemeral Keys (ECDHE) support to Red Hat Enterprise Linux 7 *Sendmail*. ECDHE is a variant of the Diffie-Hellman protocol that uses elliptic curve cryptography

This blog shows an easy way to determine supported outbound (client) cipher suites in PI / PO. The key element to determine the supported cipher suites in an easy way is to use the internet tool How' ecdh-ecdsa-aes256-gcm-sha384 tlsv1.2 kx=ecdh/ecdsa au=ecdh enc=aesgcm(256) mac=aead: ecdh-rsa-aes256-sha384 tlsv1.2 kx=ecdh/rsa au=ecdh enc=aes(256) mac=sha384: ecdh-ecdsa-aes256-sha384 tlsv1.2 kx=ecdh/ecdsa au=ecdh enc=aes(256) mac=sha38 # openssl ciphers -v 'high:!sslv2:!adh:!dhe:!dh:!3des:!md5:!anull:!enull:!null:@strength' ecdhe-rsa-aes256-gcm-sha384 tlsv1.2 kx=ecdh au=rsa enc=aesgcm(256) mac=aead ecdhe-ecdsa-aes256-gcm-sha384 tlsv1.2 kx=ecdh au=ecdsa enc=aesgcm(256) mac=aead ecdhe-rsa-aes256-sha384 tlsv1.2 kx=ecdh au=rsa enc=aes(256) mac=sha384 ecdhe-ecdsa-aes256-sha384 tlsv1.2 kx=ecdh au=ecdsa enc=aes(256) mac=sha384.
