“…As WSNs are resource-constrained, techniques that are more lightweight, such as symmetric ones (XOR and hash computations, for example), are more appropriate [4]. However, efficient ECC implementations in resource-constrained sensor motes have continued to be proposed [28]- [30], thus increasing the feasibility and practicality of ECC in IoT devices. Moreover, although we employ ECC to address the security weaknesses found in Adavoudi-Jolfaei et al's scheme, ECC operations are performed by users, authentication and authorization servers, and gateways with fewer resource constraints than sensor nodes.…”

Wireless sensor networks (WSNs) have played an important role in the Internet of Things (IoT), and the 5G network is being considered as a major candidate for IoT's communication network with the advent of 5G commercialization. The potential of integrating WSNs and 5G in the IoT is expected to allow IoT to penetrate deeply into our daily lives and to provide various services that are convenient, but at the same time, it also brings new security threats. From this aspect, user authentication and key agreement are essential for secure end-to-end communication. As IoT devices, including sensors, collect and process more and more personal information, both anonymous authentication and authorization are also required to protect the privacy and to prevent anyone without privileges from accessing private data. Recently, Adavoudi-Jolfaei et al. proposed an anonymous three-factor authentication and access control scheme for real-time applications in WSNs. However, we found that this scheme does not provide sensor-node anonymity and suffers from user collusion and desynchronization attacks. In this paper, we introduce a system architecture by considering the integration of WSNs and 5G for IoT. Based on a cryptanalysis of Adavoudi-Jolfaei et al.'s scheme and the system architecture, we propose an elliptic curve cryptography (ECC)-based privacy-preserving authentication, authorization, and key agreement scheme for WSNs in 5G-integrated IoT. We conduct a formal and informal security analysis in order to demonstrate that the proposed scheme withstands various security attacks and guarantees all desired security features, overcoming the drawbacks of Adavoudi-Jolfaei et al.'s scheme. Finally, a performance and comparative analysis with the related schemes indicate that the proposed scheme is both efficient and more secure.

“…While symmetric key cryptography is simpler and can be implemented efficiently on WSN nodes, public key cryptography (PKC) is significantly more complex and yet still needed for the distribution of the symmetric keys [9]. Elliptic-curve cryptography (ECC) [10,11] is a commonly used public-key cryptosystem and considered a viable remedy for distributing the secret keys in WSNs [12][13][14][15][16]. The efficiency of ECC depends on the speed of the performed arithmetic.…”

“…For energy-harvesting wireless sensor nodes, it is a concern whether the sensor node is able to perform a powerhungry cryptographic algorithm within the limitations of the harnessed power obtained through solar energy, mechanical vibration, electromagnetic radiation, etc. added In [16], a competent ECC implementation on the constrained MSP430 microcontroller is proposed over the optimal extension field (OEF) GF ((2 13 − 1) 13 ) [26]. The implementation uses the number theoretic transform and Edwards curve point arithmetic.…”

ECC is a popular cryptographic algorithm for key distribution in wireless sensor networks where power efficiency is desirable. A power efficient implementation of ECC without using hardware multiplier support was proposed earlier for wireless sensor nodes. The proposed implementation utilized the number theoretic transform to carry operands to the frequency domain, and conducted Montgomery multiplication, in addition to other finite field operations, in that domain. With this work, we perform in the frequency domain only polynomial multiplication and use the fast Fourier transform to carry operands between the time and frequency domains. Our ECC implementation over GF ((2 13 − 1) 13 ) on the MSP430 microcontroller implements multiplications without using a hardware multiplier. It achieves scalar multiplication with fixed and random points in only 0.89 s and 1.74 s, respectively. Our implementation achieves ECC point multiplication of fixed and random points 10% and 13% faster, and consuming 12% and 15% less energy, in comparison to the existing work.

“…Public key cryptography (PKC) [19] provides a solution to the key distribution problem, yet it is considered computationally expensive for constrained WSN nodes. On the other hand, previous works prove PKC to be applicable on constrained WSN nodes for solving the key distribution problem [20][21][22][23][24]. Elliptic curve cryptography (ECC) [25,26] is a popular option for PKC.…”

We implement elliptic curve cryptography on the MSP430 which is a commonly used microcontroller in wireless sensor network nodes. We use the number theoretic transform to perform finite field multiplication and squaring as required in elliptic curve scalar point multiplication. We take advantage of the fast Fourier transform for the first time in the literature to speed up the number theoretic transform for an efficient realization of elliptic curve cryptography. Our implementation achieves elliptic curve scalar point multiplication in only 0.65 s and 1.31 s for multiplication of fixed and random points, respectively, and has similar or better timing performance compared to previous works in the literature.
