Dear Farhad,

Sure, the thing you need to do is to call mbedtls_ssl_conf_authmode( conf, MBEDTLS_SSL_VERIFY_REQUIRED ) where conf is the ssl_config of the server. For more details, see that function's documentation (in ssl.h). For an example, see the command-line option auth_mode in programs/ssl/ssl_server2.c.

Hope this helps!

Best regards, Manuel

Dear,

I would like to have mutual authentication using dtls_client.c and dtls_server.c examples. In the current version of the example, the client does not send his own certificate and the server does not verify the certificate of the client. Could you please provide me the changes that I need to make in both dtls_client.c and dtls_server.c examples?
