Résumé :

Authentication is an important aspect for security in any cryptographic application. For Wireless Sensor Networks (WSN), authentication of a message is a vital concern. Authentication is provided through digital signature, and the cost of signing a message is a crucial factor due to the resource constraint nature of a sensor mote. So, there is a need to optimize the cost of computations, involved in the digital signature. In this paper, we present a Pairing-Free Identity Based digital Signature (PF-IBS) algorithm for WSN. PF-IBS is proven secure in terms of existential UnForgeability in the random oracle model against Adaptive Chosen Message Attack (UF-PF-IBS-ACMA). For the performance evaluation of the PF-IBS algorithm, the experimental setup includes MICAz sensor mote with TinyOS and RELIC-Toolkit cryptographic library. The results are gathered with the help of an emulator AVRORA.
