Abstract
To keep a network secure, a user authentication scheme that allows only authenticated users to access network services is required. However, the limited resources of sensor nodes make providing authentication a challenging task. We therefore propose a new method of security for a wireless sensor network (WSN). Our technique, Secure User Biometric Based Authentication Scheme (SUBBASe), is based on the user biometrics for WSNs. It achieves a higher security level as well as improved network performance. This solution consists of easy operations and light computations. Herein, the proposed technique is evaluated and compared with previous existing techniques. This scheme increases the performance of the network by reducing network traffic, defending against DOS attacks, and increasing the battery life of a node. Consequently, the functionality and performance of the entire network is improved.

IntroductionTiny sensor nodes in the network process information they receive after sensing their surroundings
Wireless sensor networks (WSNs) contain sensor nodes for specific purposes [1]
An attacker cannot steal user information from a trusted and/or sensor node. Schemes that preserve such password tables to confirm a user login may suffer from this type of attack. This threat is solved with Secure User Biometric Based Authentication Scheme (SUBBASe); because user biometrics is used for the network login
Summary
Tiny sensor nodes in the network process information they receive after sensing their surroundings. Such networks can be applied to a large number of applications including structural health monitoring, environmental control, and battlefield surveillance [2]. Sensed data may be confidential, and illegal users can access sensitive data by sending a request to a sensor node Because it is difficult for a sensor node to authenticate a request message, the leakage of sensitive information and an unnecessary depletion of network resources, e.g., node power and network bandwidth, may occur. User authentication is a required service to resist the illegal use of network data and resources [4] To accomplish this, it is very important for sensor nodes to authenticate the identities of users.
