A device that terminates the DTLS security (CoAPS) and then talks to the CA is a Registration Authority according to EST and RFC5280. It's not a proxy.

A device that terminates the DTLS security (CoAPS) and then talks to the CA is a Registration Authority according to EST and RFC5280. It's not a proxy. (And it doesn't matter if it speaks HTTPS or CMS or CMP or super-pigeon-telepathy to the CA) A http/coap proxy is specified in RFC8075. It explains "how an HTTP request is mapped to a CoAP request and how a CoAP response is mapped back to an HTTP response". In the est-coap draft DTLS and TLS connections are terminated in the http/coap proxy, and the proxy is therefore connected to an RA (possibly running on the same host as the proxy). Where is my terminology going astray? Peter ___ Ace mailing list Ace@ietf.org https://www.ietf.org/mailman/listinfo/ace
