A certificateless signcryption scheme for smart home networks

Abstract

Smart home networks (SHNets) are based on the Internet of Things (IoT) and provide users with a highly intelligent home life. In recent years, SHNets have become more and more popular. In SHNets, a large amount of data interactions are needed. These data related to the privacy of users may be subject to attacks such as eavesdropping attacks, replay attacks, and mobile phone stolen attacks. Privacy protection and communication security in smart home networks have been widely studied by many scholars. However, most of the existing user authentication in current researches focus on identity-based authentication, where the encryption protocols are divided into two steps: the signing step and the encryption step. In this paper, a certificateless signcryption scheme for SHNets is proposed which can provide biometric-based user identity authentication. The security and performance analyses show that our scheme is efficient and secure.

An Efficient Online/Offline Signcryption Scheme for Internet of Things in Smart Home

“…In 2018, Sai et al [21] introduce an effective certificateless online/offline signcryption scheme that can offer Wireless Communications and Mobile Computing biometric authentication for user identity. Regrettably, the proposed approach is based on bilinear pairing.…”

“…Computation Time. This section presents the comparison of the proposed framework with some relevant online/ offline signcryption approaches cited [18][19][20][21] in terms of computational time with including parameters Bilinear Pairing Operations (BPO), Bilinear Pairing Multiplication (BPM), EXxponentiations (EX), and Hyperelliptic Curve Devisor Multiplication (HCDM). The running operational time of the given parameters is taken from [23][24][25].…”

“…Communication Overhead. In this section, we compare the proposed framework with some relevant online/offline signcryption approaches cited [18][19][20][21] in terms of communication overhead with the including parameters bilinear pairing and Hyperelliptic Curve Cryptosystem. The bits size of the given parameters is taken from [24,25].…”

“…The bits size of the given parameters is taken from [24,25]. Table 4 shows the communication overhead of the aforementioned parameters in the proposed framework and the relevant online/offline signcryption schemes cited [18][19][20][21]. Lastly, Figure 4 clearly demonstrates the efficiency of the proposed framework in terms of communication overhead.…”
