However, even for already certified devices, security protocols have to be updated when a breach is found or a certain version becomes obsolete. Many approaches for securing IoT applications are nowadays based on the integration of a security layer [e.g., using transport layer security, (TLS)], but this may result in difficulties when upgrading the security algorithms, as the whole application has to be updated. This fact may shorten the life of IoT devices. As a way to overcome these difficulties, this paper presents IoTsafe, a novel approach relying on secure socket shell (SSH), a feasible alternative to secure communications in IoT applications based on hypertext transfer protocol (HTTP and HTTP/2). In order to illustrate its advantages, a comparison between the traditional approach (HTTP with TLS) and our scheme (HTTP with SSH) is performed over low-power wireless personal area networks (6loWPAN) through 802.15.4 interfaces. The results show that the proposed approach not only provides a more robust and easy-To-update solution, but it also brings an improvement to the overall performance in terms of goodput and energy consumption. Core server stress tests are also presented, and the server performance is also analyzed in terms of RAM consumption and escalation strategies. 000079014 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón$$9info:eu-repo/grantAgreement/ES/DGA/T31-17R$$9info:eu-repo/grantAgreement/ES/MINECO/TIN2015-64770-R-TISFIBE$$9info:eu-repo/grantAgreement/ES/MINECO/TIN2016-76770-R 000079014 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079014 590__ $$a3.745$$b2019 000079014 591__ $$aCOMPUTER SCIENCE, INFORMATION SYSTEMS$$b35 / 156 = 0.224$$c2019$$dQ1$$eT1 000079014 591__ $$aENGINEERING, ELECTRICAL & ELECTRONIC$$b61 / 266 = 0.229$$c2019$$dQ1$$eT1 000079014 591__ $$aTELECOMMUNICATIONS$$b26 / 90 = 0.289$$c2019$$dQ2$$eT1 000079014 592__ $$a0.775$$b2019 000079014 593__ $$aComputer Science (miscellaneous)$$c2019$$dQ1 000079014 593__ $$aEngineering (miscellaneous)$$c2019$$dQ1 000079014 593__ $$aMaterials Science (miscellaneous)$$c2019$$dQ2 000079014 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000079014 700__ $$0(orcid)0000-0002-6977-6363$$aSaldaña, J.$$uUniversidad de Zaragoza 000079014 700__ $$0(orcid)0000-0002-5237-0447$$aFernandez-Navajas, J.$$uUniversidad de Zaragoza 000079014 700__ $$0(orcid)0000-0003-4690-6089$$aRuiz-Mas, J.$$uUniversidad de Zaragoza 000079014 7102_ $$15008$$2560$$aUniversidad de Zaragoza$$bDpto.
