Abstract

The Constrained Application Protocol (CoAP) is a web transfer protocol designed for resource limited nodes in constrained networks. For securing the protocol, CoAP defines a binding to Datagram Transport Layer Security (DTLS) with four security modes. One of them is the Certificate mode where the device has an asymmetric key pair with an X.509 certificate. However, the intrinsic properties of x.509 certificates impede the application on the resource constrained nodes. This draft describes the necessary adjustments and derives a modified profile for X.509 certificates to cope with the resource limitations of low-power low-performing devices
