Line 328: * Certificate, where DTLS is enabled and the device uses [[X.509]] certificates for validation. Research has been conducted on optimizing DTLS by implementing security associates as CoAP resources rather than using DTLS as a security wrapper for CoAP traffic. This research has indicated that improvements of up to 6.5 times none optimized implementations.<ref name="Security as a CoAP resource: An optimized DTLS implementation for the IoT">{{cite book \|last1=Capossele \|first1=Angelo \|last2=Cervo \|first2=Valerio \|last3=De Cicco \|first3=Gianluca \|last4=Petrioli \|first4=Chiara\|title=2015 IEEE International Conference on Communications (ICC) \|chapter=Security as a CoAP resource: An optimized DTLS implementation for the IoT \|author4-link= Chiara Petrioli \|date=June 2015 \|~~journal~~publisher=IEEE \|pages=529–554 \|doi= 10.1109/ICC.2015.7248379\|isbn=978-1-4673-6432-4 \|s2cid=12568959 }}</ref> In addition to DTLS, RFC8613<ref>{{Cite journal\|last1=Palombini\|first1=Francesca\|last2=Seitz\|first2=Ludwig\|last3=Selander\|first3=Goeran\|last4=Mattsson\|first4=John\|title=Object Security for Constrained RESTful Environments (OSCORE)\|url=https://tools.ietf.org/html/rfc8613.html\|access-date=2021-05-07\|website=tools.ietf.org\|year=2019 \|doi=10.17487/RFC8613 \|s2cid=58380874 \|language=en}}</ref> defines the Object Security for Constrained RESTful Environments ([[OSCORE]]) protocol which provides security for CoAP at the application layer.
