“…The results of the comparison are in the Table 2 and Figure 1 to 5. 2) Our concrete scheme satisfies the requirements of unforgeability in [28] as we demonstrated our security proofs in Section IV-A. 3) Our concrete scheme provides a signer privacy preservation in the aspect of deniability; hence, none other than designated verifier can verify the validity of the signature.…”

“…Huang et al was first introduced the notion of certificateless designated verifier signature schemes in [18]. Recently, many certificateless designated verifier signature schemes were proposed [13], [22], [28], [31]. Rastegari et al [28] provided intensive security reviews on certificateless designated verifier signature schemes and they gave a conclusion on the suitable security model for certificateless designated verifier signature schemes.…”

In recent years, the Internet of Things (IoT) devices have become increasingly deployed in many industries and generated a large amount of data that needs to be processed in a timely and efficient manner. Using aggregate signatures, it provides a secure and efficient way to handle large numbers of digital signatures with the same message. Recently, the privacy issue has been concerned about the topic of data sharing on the cloud. To provide the integrity, authenticity, authority, and privacy on the data sharing in the cloud storage, the notion of an aggregatable certificateless designated verifier signature scheme (ACLDVS) was proposed. ACLDVS also is a perfect tool to enable efficient privacy-preserving authentication systems for IoT and or the vehicular ad hoc networks (VANET). Our concrete scheme was proved to be secured underling of the Computational Diffie-Hellman assumption. Compared to other related schemes, our scheme is efficient, and the signature size is considerably short.

Public Key Infrastructure (PKI) is a comprehensive information security framework for providing secure information and communication over the internet. Its need and use has grown over the years and continually grows. This research work examines the current PKI framework's validation process as operated by vendors and subscribers to identify the drawbacks and propose enhanced approaches to its validation mechanism. Using an approach of reviewing secondary data, critical weaknesses of integrity, proof of trust and single point-of-failure were identified with the current PKI framework. This study therefore advances proposed solutions to address the identified weaknesses by specifically introducing multiple Certificate Authorities, storage, visibility and searchability of subscriber information in public repository. A comprehensive detail of its implementation is proposed to address the identified weaknesses of uncertain integrity, trust for certificate authorities and prevent a single point of failure. Furthermore, the proposed enhancements are validated with the protection motivation theory and a framework for empirically testing the enhancements is suggested. Further research would be required to factor in multi-factor authentication without compromising performance.

“…In 2019, Rastegari et al [16] further combined DVS with certificates cryptosystems and achieved a substantial system that was proved to be secure using the standard model. At present, many scholars have paid attention to the development of SDVS systems [17,18,19,20,21,22,23].…”

This paper proposes an efficient Strong Designated Multi-Verifier Signature (SDMVS) scheme for facilitating the privacy-preserving group-oriented electronic commerce applications. A Designated Verifier Signature (DVS) scheme can support online transactions that must simultaneously guarantee the property of confidentiality and authenticity since the generated signature can only be authenticated by a designated verifier. In this study, we combine the concept of DVS and multi-recipients to propose an SDMVS scheme. In particular, our mechanism further enables a group of intended recipients to examine the signature validity. All members of the designated verifier group must cooperate in carrying out the signature verification procedure. Besides, the property of non-transferability provides the designated verifier group with the ability to create another legitimate transcript that is hard to be differentiated from the original signature. The analysis results of security proof and efficiency show that the construction of our system fulfills essential security requirements, and the expansion of group size will not influence the computational costs of each party.
