In order to provide a high level of security in this environment, the moving sensor node needs to be authenticated to new neighboring nodes and a key established for secure communication. The paper proposes an efficient and scalable protocol to establish and update the authentication key in a dynamic wireless sensor network environment. The protocol guarantees that two sensor nodes share at least one key with probability 1 (100%) with less memory and energy cost, while not causing considerable communication overhead.<\/jats:p>","DOI":"10.3390\/s100403718","type":"journal-article","created":{"date-parts":[[2010,4,13]],"date-time":"2010-04-13T11:15:22Z","timestamp":1271157322000},"page":"3718-3731","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Authentication and Key Establishment in Dynamic Wireless Sensor Networks"],"prefix":"10.3390","volume":"10","author":[{"given":"Ying","family":"Qiu","sequence":"first","affiliation":[{"name":"Cryptography and Security Department, Institute for Infocomm Research, 138632, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianying","family":"Zhou","sequence":"additional","affiliation":[{"name":"Cryptography and Security Department, Institute for Infocomm Research, 138632, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joonsang","family":"Baek","sequence":"additional","affiliation":[{"name":"Cryptography and Security Department, Institute for Infocomm Research, 138632, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Javier","family":"Lopez","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Malaga, 29071 Malaga, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2010,4,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"393","DOI":"10.1016\/S1389-1286(01)00302-4","article-title":"Wireless sensor networks: a survey","volume":"38","author":"Akyildiz","year":"2002","journal-title":"Comput.
