A Survey on Authentication Schemes for Wireless Sensor Networks

Abstract

Nowadays, security is one of the main concerns in industry and academia. Complexity and number of attacks increased, which translates in higher vulnerability for end users and companies. Wireless sensors are one of the most vulnerable devices on the market due to their limited hardware and software capabilities. Attackers focus on these devices due to their limitations, with the end goal of compromising the entire workgroup or network. To counter this trend, developers and researchers started to propose different schemes and protocols that increase security. This paper has the goal of presenting a thorough analysis on existing authentication mechanisms in order to gain knowledge on the existing schemes, techniques, implementations and issues. Furthermore, with a thorough study, one can propose future implementations that may apply on different solutions.
