To this end, techniques in which the security of IoT devices is decoupled from the applications they run can provide significant benefits and enable the development of new standardization strategies. This article presents a study of the benefits provided by IoTsafe, a security decoupling approach when used in combination with the constrained application protocol (CoAP). Whereas previous work relied on HTTP/HTTP2 protocols, the present article is focused on the analysis of the feasibility of IoTsafe in more constrained devices in channels with high interference levels. The benefits of this technique are illustrated by means of a battery of tests to evaluate the impact of this scheme. The results show no performance penalty (taking CoAP with security as a baseline) in lossless channels, even when an overhead increment of 38 is borne. Furthermore, in lossier channels, a transfer time reduction of 36 is achieved, a figure that increases significantly if traffic compression is enabled. 000165837 536__ $$9info:eu-repo/grantAgreement/ES/DGA/T31-17R 000165837 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000165837 590__ $$a9.471$$b2020 000165837 591__ $$aCOMPUTER SCIENCE, INFORMATION SYSTEMS$$b6 / 161 = 0.037$$c2020$$dQ1$$eT1 000165837 591__ $$aTELECOMMUNICATIONS$$b6 / 91 = 0.066$$c2020$$dQ1$$eT1 000165837 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b15 / 273 = 0.055$$c2020$$dQ1$$eT1 000165837 592__ $$a2.075$$b2020 000165837 593__ $$aComputer Networks and Communications$$c2020$$dQ1 000165837 593__ $$aComputer Science Applications$$c2020$$dQ1 000165837 593__ $$aSignal Processing$$c2020$$dQ1 000165837 593__ $$aInformation Systems$$c2020$$dQ1 000165837 593__ $$aInformation Systems and Management$$c2020$$dQ1 000165837 593__ $$aHardware and Architecture$$c2020$$dQ1 000165837 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000165837 700__ $$0(orcid)0000-0002-6977-6363$$aSaldaña, José$$uUniversidad de Zaragoza 000165837 700__ $$0(orcid)0000-0002-5237-0447$$aFernández-Navajas, Julián$$uUniversidad de Zaragoza 000165837 700__ $$0(orcid)0000-0003-4690-6089$$aRuiz-Mas, José$$uUniversidad de Zaragoza 000165837 7102_ $$15008$$2560$$aUniversidad de Zaragoza$$bDpto.
