However, even today, it is equally important for the measures employed to be energy efficient. For this reason, this publication analyzes the suitability of various cryptographic primitives for use in WSNs according to various criteria and, finally, describes a modular, PKI-based framework for confidential, authenticated, secure communications in which most suitable primitives can be employed. Due to the limited capabilities of common WSN motes, criteria for the selection of primitives are security, power efficiency and memory requirements. The implementation of the framework and the singular components have been tested and benchmarked in our testbed of IRISmotes."],["dc.identifier.doi","10.3390/s150819560"],["dc.identifier.isi","000360906500089"],["dc.identifier.pmid","26266413"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12146"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/36367"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Mdpi Ag"],["dc.relation.issn","1424-8220"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0/"],["dc.title","Secure and Authenticated Data Communication in Wireless Sensor Networks"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

We propose intelligent quantization mechanisms for key generation, achieving high secret bits generation rate.

Mainly, we investigate the effects of delay and mobility on the performance and we enhance the key generation mechanism accordingly.

The framework provides a fast re-authentication mechanism to authenticate a mobile node that moves through different domains without the need to communicate with the home domain. We model the protocol using the high level protocol specification language (HLPSL) and we verify our model using the AVISPA model checking tool. Two main security properties are checked: authenticity and secrecy. We consider different scenarios in order to verify the protocol.
