    abstract =  {Low-resource devices in a Low-power and Lossy Network (LLN) can operate in a mesh network using the IPv6 over Low-power Wireless Personal Area Networks (6LoWPAN) and IEEE 802.15.4 link-layer standards. Enrollment over Secure Transport (EST) {[}RFC7030{]} is used for authenticated/authorized endpoint certificate enrollment (and optionally key provisioning) through a Certificate Authority (CA) or Registration Authority (RA). Example low-resource uses cases for EST are: secure bootstrapping and certificate enrollment. Low-resource devices often use the lightweight Constrained Application Protocol (CoAP) {[}RFC7252{]} for message exchanges. This document defines how low-resource devices are expected to use EST over secure CoAP (EST-coaps). 6LoWPAN fragmentation management and extensions to CoAP registries are needed to enable EST-coaps.},
