For such a network to be viable, its design must protect data privacy and authenticity given that medical data are highly sensitive. We identify the unique security challenges of such a sensor network and propose a set of resource-efficient mechanisms to address these challenges. Our solution includes (1) a novel two-tier scheme for verifying the authenticity of patient data, (2) a secure key agreement protocol to set up shared keys between sensor nodes and base stations, and (3) symmetric encryption\/decryption for protecting data confidentiality and integrity. We have implemented the proposed mechanisms on a wireless mote platform, and our results confirm their feasibility.<\/jats:p>","DOI":"10.3390\/s90806273","type":"journal-article","created":{"date-parts":[[2009,8,11]],"date-time":"2009-08-11T11:07:49Z","timestamp":1249988869000},"page":"6273-6297","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Design and Implementation of a SecureWireless Mote-Based Medical Sensor Network"],"prefix":"10.3390","volume":"9","author":[{"given":"Kriangsiri","family":"Malasri","sequence":"first","affiliation":[{"name":"Department of Computer Science, University of Memphis, 209 Dunn Hall, Memphis, TN 38152-3240, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lan","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Computer Science, University of Memphis, 209 Dunn Hall, Memphis, TN 38152-3240, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,8,11]]},"reference":[{"key":"ref_1","unstructured":"Gellersen, H.W., Want, R., and Schmidt, A.
