“…We now revisit Wang et al’s certificateless signature scheme [ 28 ], and demonstrate that the scheme is insecure against a super type I adversary. Revisiting the scheme: In the Setup phase, KGC generates a group G of elliptic curve points with prime order n and determines a generator P of G , prior to randomly selecting a master secret key

and computing the master public key

“…In recent years, designing certificateless signature schemeswithout bilinear pairings has been extensively studied due to its effectiveness in solving the key escrow problem in identity-based cryptography, and its potential for deployment in an environment comprising resource-limited mobile devices. In this section, we first present the state-of-the-art of certificateless signature before revealing a previously unknown weakness in a recent certificateless signature mechanism proposed by Wang et al [ 28 ]. We then present a comparative summary of our proposed scheme and relevant schemes.…”

“…The authors then proposed a countermeasure for the identified attacks in which the robustness against super type I and II adversaries can be guaranteed. In a latter work, Wang et al [ 28 ] re-designed the communication procedures of the certificateless signature mechanism proposed by Yeh et al [ 30 , 31 ] to enhance the computation efficiency. Specifically, costs associated with ECC-based scalar multiplication and addition operations of points are removed.…”

“…We now benchmark the security and performance of the proposed certificateless signature with those of Gong and Li [ 29 ], Wang et al [ 28 ] and Tsai [ 16 ]. From Table 7 , we observe that our proposed scheme and Tsai’s scheme [ 16 ] enjoy the same security level–resilience to super type I and II adversaries.…”

Rapid advances in wireless communications and pervasive computing technologies have resulted in increasing interest and popularity of Internet-of-Things (IoT) architecture, ubiquitously providing intelligence and convenience to our daily life. In IoT-based network environments, smart objects are embedded everywhere as ubiquitous things connected in a pervasive manner. Ensuring security for interactions between these smart things is significantly more important, and a topic of ongoing interest. In this paper, we present a certificateless signature scheme for smart objects in IoT-based pervasive computing environments. We evaluate the utility of the proposed scheme in IoT-oriented testbeds, i.e., Arduino Uno and Raspberry PI 2. Experiment results present the practicability of the proposed scheme. Moreover, we revisit the scheme of Wang et al. (2015) and revealed that a malicious super type I adversary can easily forge a legitimate signature to cheat any receiver as he/she wishes in the scheme. The superiority of the proposed certificateless signature scheme over relevant studies is demonstrated in terms of the summarized security and performance comparisons.

“…The malicious-but-passive KGC adversary sets some trapdoors in the system parameters and the master secret key and then uses these trapdoors to launch malicious attacks to compromise the security of the CLS scheme. However, some existing CLS schemes [6][7][8] have been shown to be insecure against malicious-but-passive KGC attacks.…”

The certificateless aggregate signature (CLAS) scheme is a very important data aggregation technique that compresses a large number of signatures from different users into a short signature. CLAS can reduce the total length of a signature and the computational overhead of signature verification and is therefore highly suitable for resource-constrained network environments. Many CLAS schemes have been proposed in recent years, but the construction of a secure and efficient CLAS scheme remains important. In 2018, Li et al. found that the CLAS scheme proposed by He et al. could not resist malicious-but-passive KGC attacks, and they presented an improved CLAS scheme. Du et al. proposed a CLAS scheme with the constant aggregate signature length and claimed that their scheme was resistant to forgery attacks. Chen et al. designed a CLAS scheme with efficient verification and proved that their CLAS scheme was secure in the random oracle model. In this paper, we demonstrate that Li et al. 's CLAS scheme, Du et al. 's CLAS scheme, and Chen et al. 's CLAS scheme are insecure against coalition attacks and present concrete examples. That is, an attacker can forge a valid aggregate signature using some illegal single signatures. To withstand suck attacks, we propose an improved CLAS scheme based on Chen et al. 's CLAS scheme.

The Named Data Networking (NDN) architecture, known for its caching strategies and name‐based routing, is an exemplary paradigm for content distribution across Internet of Things (IoT) devices. In the environment of NDN‐IoT, there is an urgent demand for a lightweight signature authentication scheme suitable for terminal devices to ensure the integrity of Data packets and the legitimacy of their sources. Many researchers opt for employing certificateless public key cryptography measures to enhance the security of communication among terminal devices in NDN‐IoT. However, among the array of proposed solutions, issues such as lack of resistance against signer identity exposure, susceptibility to man‐in‐the‐middle attacks, and replay attacks persist. Some researchers advocate for partitioning the devices in NDN‐IoT into different zones, yet there remains a deficiency in the design of packet exchange mechanisms across distinct zones. To address these issues, this paper proposes a novel blockchain‐based certificate‐less signature scheme in the NDN‐IoT environment that integrates key features such as distributed legitimate producer management, inter‐domain interaction mechanisms, anonymous identity protection, and blockchain storage optimization. The overarching goal is to provide robust security services for resource‐constrained devices within the NDN infrastructure while ensuring authenticity and integrity of data packets while alleviating the burden of certificate management on end devices. Compared to similar existing solutions, our proposed method incurs only 34% of the computational overhead required for Data packet signature verification, while maintaining equivalent cache occupancy and achieving higher security performance.
