Secured and flexible user authentication protocol for wireless sensor network

Abstract

PurposeIn wireless sensor network (WSN), user authentication plays as a vital role in which data sensing, as well as sharing, will be spoiled by hackers. To enhance user security, user authentication must be focused.Design/methodology/approachIn previous works, for secured authentication, Enhanced User Authentication Protocol (EUAP) is presented. On the other hand, the user free password generation is permitted in the previous technique.FindingsHere, password leakage may cause a malevolent user's contribution to the WSN environment. By presenting the Flexible and Secured User Authentication Protocol (FSUAP), this is solved in the presented technique in which secured as well as reliable sharing of data contents via unsecured wireless sensor devices was accomplished.Originality/valueThe foremost objective of the present technique is to device the protocol that would verify the users beforehand letting them access the sensor devices situated in various sites. The use of a sensor device could be reduced in a significant way. Three-factor authentication protocols are presented in place of two-factor authentication protocol in the presented technique that could deal with and safeguard the environment from a brute force attack in an effective manner.

Secure Multimodal Authentication Scheme for Wireless Sensor Networks

“…Calculating hamming distances between generated keys tested distinctive of keys while verification of random biometric keys was done using NIST (National Institute of Standards and Technology) statistical test suite. A secured and reliable protocol to share data contents through unsecure wireless sensor device was developed by Prabhu and Senthilnathan [27]. The proposed Flexible and Secured User Authentication Protocol (FSUAP) addressed the issues of Enhanced User Authentication Protocol (EUAP) and password leakage in the WSN environment.…”
