This network requires secure and private means of communications. The building blocks of the Internet of Things are devices manufactured by various producers and are designed to fulfil different needs. There would be no common hardware platform that could be applied in every scenario. In such a heterogeneous environment, there is a strong need for the optimization of interoperable security. We present optimized elliptic curve Cryptography algorithms that address the security issues in the heterogeneous IoT networks. We have combined cryptographic algorithms for the NXP\/Jennic 5148- and MSP430-based IoT devices and used them to created novel key negotiation protocol.<\/jats:p>","DOI":"10.3390\/s150921478","type":"journal-article","created":{"date-parts":[[2015,9,1]],"date-time":"2015-09-01T10:55:58Z","timestamp":1441104958000},"page":"21478-21499","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Optimized ECC Implementation for Secure Communication between Heterogeneous IoT Devices"],"prefix":"10.3390","volume":"15","author":[{"given":"Leandro","family":"Marin","sequence":"first","affiliation":[{"name":"Department of Applied Mathematics, Computer Sciences Faculty, University of Murcia, Regional Campus of International Excellence \"Campus Mare Nostrum\", Murcia 30100, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcin","family":"Pawlowski","sequence":"additional","affiliation":[{"name":"Institute of Information Systems, University of Applied Sciences Western Switzerland (HES-SO), Sierre 3690, Switzerland"},{"name":"Department of Information Technologies, Faculty of Physics, Astronomy and Applied Computer Science, Jagiellonian University, Krakow 30-348, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Antonio","family":"Jara","sequence":"additional","affiliation":[{"name":"Institute of Information Systems, University of Applied Sciences Western Switzerland (HES-SO), Sierre 3690, Switzerland"},{"name":"Research and Development Department, HOP Ubiquitous, 30562 Ceuti, Murcia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,8,28]]},"reference":[{"key":"ref_1","unstructured":"Patrick, G., and Peter, F.
