“…Later, Galindo and Garcia designed a scheme by utilizing the technique used in Schnorr signature scheme for generating the private key (used by the PKG), as well as the signature (by the third party). After that, Wang proposed a fuzzy IDS scheme under the ROM without considering bilinear pairing operation. In 2017, Alezabi et al proposed a technique; however, emphasizing the authentication of entities' identities and reauthentication after renewing the entities' identities makes this method not very suitable for the different types of resource constrained devices.…”

Crowdsensing utilizes the wisdom of crowd by sensing the information through different types of smart devices such as a smartphone, tablet, and sensors to serve the problem of common interests. It can be achieved by the concept of Internet of Things (IoT), which considers a large set of smart sensing interconnected devices. However, these devices are resource constrained in terms of storage, infrastructure, and computation power, and therefore, cloud technology is required. In order to minimize the storage overhead, only authentic extracted information from crowdsourcing is desirable to store in the cloud space. A number of signature‐based authentication schemes have been designed using either bilinear pairing or random oracle model (ROM) for the IoT devices. However, due to the high computational pairing cost and improper ROM implementation, schemes are found to be inefficient and vulnerable under the chosen‐message and chosen‐ID attack. To reduce the computational cost, we propose a pairing‐free quadratic residue–based signature scheme that authenticates IoT devices and cloud centric data. In addition, the proposed signature does not consider ROM, and it is secure in the standard model based on the proposed modified interactive quadratic residuosity assumption. Performance evaluation and comparisons ensure that our scheme is more efficient than earlier related schemes.

“…Later on, Boneh and Franklin instantiated Shamir's idea and implemented IBE using bilinear pairing over elliptic curve (EC) points, Subsequently, several modifications and enhancements based on Boneh and Franklin's IBE have been proposed, and their safety based on the standard security assumption and model have been presented . On the other side, several ID‐based signature and authentication schemes were proposed in the literature. Due to several kind of attacks, like mafia attacks and blackmailing, a special kind of signature called designated verifier signature (DVS) scheme was proposed by Jakobsson et al The concept was introduced due to the fact that a signer has no knowledge about to whom (s)he is generating the signature.…”

With the rapid developments in embedded sensor technology, the internet of things (IoT) becomes the most focused research trend in the recent years. However, the integration of such technology into mobile crowdsensing networks results in many security challenges. Data confidentiality and authenticity are the two key privacy concerns in any IoT‐based crowdsensing environment. Focusing on these security issues, we present a new cryptographic protocol to meet those challenges. Our protocol is based on two new schemes; first is an encryption scheme, which utilizes the idea of identity‐based encryption, and the second is a designated verifier signature scheme. Here, we design a pairing‐free and random oracle‐free encryption scheme with a small‐size public parameter where the anonymity of IoT‐recipient is maintained. Besides, the proposed designated verifier signature scheme facilitates the signatory to send a signature without sending the original message. The security of the encryption and signature schemes are proven in the standard security model based on the difficulty of proposed modified interactive quadratic residuosity “(MIQR)” assumption. Moreover, the schemes are compared with other relevant schemes and found several merits in terms of functionality. Thus, the proposed protocol is applicable in many IoT‐enabled crowdsourcing environments where the authenticity of confidential data is the major concern.

“…And it also solves the public key management problem existed in public-key setting, Therefore, certificateless public key cryptography has interested many researchers. Many certificateless public key cryptography have been proposed, such as [9], [10], [11], [12], [13], [14].…”

Certificateless cryptography avoids the key escrow problem in identity-based crytosystems and certificate management in traditional public-key crytosystems, it has been researched by many scholars and many certificateless signature schemes have been proposed. However, most of them exist some security drawbacks and are insecure for some kinds of attacks.In this paper, we analyze two certificateless signature schemes and one proxy re-signature scheme proposed by some scholars recently. And we show that these schemes are insecure and also present the detailed attack steps. In order to overcome this problem, we also address some improved schemes which have the same or better performance than the original schemes.
