An Efficient and Provably Secure Certificateless Key-Encapsulated Signcryption Scheme for Flying Ad-hoc Network

Abstract

A Flying Ad-hoc Network (FANET) consists of Unmanned Aerial Vehicles (UAVs) tasked to handle the communication jobs in a multi-hop ad-hoc fashion. Unlike its predecessors, i.e. Mobile Ad-hoc Networks (MANETs) and Vehicular Ad-hoc Networks (VANETs), a FANET promises uninterrupted connectivity, especially during events that are temporary and stipulate a massive audience reach. However, usually, the participating UAVs in a FANET environment are resource-constrained and are, therefore, prone to cyber-attacks. In order to resolve the issue and to enable a secure communication between the UAVs and the Base Station (BS), we propose a Certificateless Key-Encapsulated Signcryption (CL-KESC) scheme. The scheme is based on the concept of Certificateless Public Key Cryptography (CL-PKC). Since CL-PKC is immune to key escrow problems and thus one of the major drawbacks of the Identity-based Public Key Cryptography (ID-PKC) is addressed. Unfortunately, the existing construction models of CL-KESC rely on elliptic curve-based operations, which are computationally expensive for small UAVs. To counter the issue, in this paper, we present a new construction model of CL-KESC based on Hyperelliptic Curve Cryptography (HECC). HECC is an advanced version of the elliptic curve and is characterized by smaller parameter and key size. The key size stretches to a maximum of 80-bits, as opposed to the elliptic curve that demands a 160-bits key size. The proposed scheme proved to be superior, chiefly in terms of security and performance, as demonstrated by the results obtained from the security verification and by carrying out comparative analysis with the existing counterparts.

“…According to [61], B will consume 14.90ms, M will consume 0.97ms.Supposing the same system environment provided in [61]ĥ DM will take 0.48ms respectively [58], [62].…”

An Online-Offline Certificateless Signature Scheme for Internet of Health Things

“…A workstation with the following requirements is used for evaluating simulation results: Intel Core i7-4510U Processor @ 2.0 GHz, 8 GB RAM, and Windows 7 Home Standard 64-bit Operating System [ 29 ]. The hyperelliptic curve divisor multiplication (HM) is believed to be 0.48 milliseconds in length due to a smaller key size of 80 bits [ 31 – 34 ]. It is apparent from the results in Tables 2 and 3 that our solution is much more effective in terms of the computational cost as shown in Figure 2 .…”

A Lightweight Nature Heterogeneous Generalized Signcryption (HGSC) Scheme for Named Data Networking-Enabled Internet of Things

“…The scheme reduces the computation and communication costs by the use of the elliptic curve cryptosystem. Zhou et al in 2017 [29] proposed a GSC scheme for security insurance in cloud storage. Zhang et al in 2018 [30] proposed an efficient CGS scheme that is suitable for low power and low processor devices due to the use of the elliptic curve cryptosystem.…”

“…In 2019, Zhou [31] improved the scheme of Zhang et al [30] and proposed a new scheme for the mobile health system that can monitor the human body status in real time. Waheed et al in 2019 [32] analyzed the proposed scheme of Zhou et al [29] and proved that the scheme of Zhou et al [29] is insecure against ciphertext indistinguishability under adaptive chosen-ciphertext attacks (IND-CCA2). Further, the 3 Wireless Communications and Mobile Computing author proposed a new and improved scheme at the same cost which is secure against the aforementioned attacks.…”
