Abstract

The main goal of Network Coding (NC) is to find an optimal transmission of data in a network. NC presents an advantage for wireless sensor networks (WSNs) in term of network lifetime. However, the Network Coding-enabled WSNs are affected by various attacks, such as pollution attacks. Many HMAC sch

Highlights

  • Wireless Sensor Networks (WSNs) [1] consist of a set of devices having limited computing resources

  • We summarize the related works of secure HMAC schemes for network coding in Table 1, in terms of vulnerability against pollution attacks

  • We present an Efficient Homomorphic MAC scheme based on multi-linear space for wireless sensor networks, called E-HMAC, to improve the security flaws of Esfahani et al.’s scheme [9]

Summary

Introduction

WSNs [1] consist of a set of devices having limited computing resources. This type of network has attracted much attention in recent years, in academia and in industry, for the study and development of a number of potential applications. The resource constraint is the most important feature of this network. Network Coding (NC) find an optimal transmission of data in a network. Network Coding can improve network resiliency against attacks. Wireless Sensor Networks (WSNs) can benefit from the benefits of NC
