Lightweight and DoS Resistant Multiuser Authentication in Wireless Sensor Networks for Smart Grid Environments

Abstract

Using a smart grid, which increases efficiency and makes it easier to monitor critical equipment in a power grid. Online real-time applications equipped with a wireless sensor network (WSN) sense and collect data in order to provide information on power generation, transmission, distribution, and customer. Applications, the administrator, and (mobile) consumers can access the WSN directly. The communications between them must be protected from adversaries to avoid false data injection, which could cause damage either to the applications, the equipment, or the sensor nodes. Another threat comes from the characteristics of the sensor nodes, which makes them vulnerable to denial of services (DoS) attacks, i.e., flooding with false messages. In this paper, a multiuser dynamic cipher puzzle (M-DCP) equipped with TinySet is proposed. This new method provides guaranteed confidentiality in the multiuser WSN authentication and lightweight DoS resistance. The M-DCP using RC5 encryption combined with the elliptic curve digital signature algorithm (ECDSA) and partial recovery can increase brute force complexity to about 1.861 × 10 137 iterations. Furthermore, the regularization of TinySet is done to simplify the administrator's task in defining the initialization parameters. The experiment showed that the regularized TinySet required less storage space with a 64-bit index than with a 32-bit index or with Counting Bloom Filter. In addition, the average query and verification time of the proposed scheme increased only by under a second or 36% compared to Counting Bloom Filter-based authentication. This is still appropriate for implementation in the WSNs.

“…The lower number of Block ( ) decreases the computation complexity. Therefore, the computation of in TT32 is lower than in TT64 [10]. This paper analyses a fixed size of and .…”

“…It was developed to decrease storage on the receiver side. This method can be implemented in the detection of RFID systems for filtering from unregistered tag [7,8], database of password systems [9], security issues [10], data science [11,12], caching management [13], etc. However, the false positive result becomes a limitation in its implementation.…”

“…The fading channels are independent quasi-static fading channels, where the fading channels remain constant for a certain coherent time but vary independently from one coherent time to another. It is also assumed that the channel gain h 0 ∼  (0, 2 0 ), and the noise in each channel also obeys Gaussian distribution with zero mean and variance 2 . In this place, we should note that the proposed method still works if the distribution of wireless channel gain changes.…”

“…[7] focuses on the microgrid domain, presenting an approach for confronting DoS attacks therein. Finally, [1] introduces multiuser dynamic cipher puzzle (M-DCP) equipped with TinySet, which is able to offer guaranteed confidentiality in the multiuser WSN authentication and lightweight DoS resistance.…”
