Blockchain technology provides efficient and secure solutions to various online activities by
utilizing a wide range of cryptographic tools. In this article, we survey the existing literature …

Multivariate Public Key Cryptosystem (MPKC) seem to be promising toward future digital
security even in the presence of quantum adversaries. MPKCs derive their security from the …

As we move into a new decade, the global world of Intelligent Infrastructure (II) services
integrated into the Internet of Things (IoT) are at the forefront of technological advancements …

In this paper, we construct the first provably-secure isogeny-based (partially) blind signature
scheme. While at a high level the scheme resembles the Schnorr blind signature, our work …

Blind signatures are a fundamental cryptographic primitive with numerous practical
applications. While there exist many practical blind signatures from number-theoretic …

Blind signatures constitute basic cryptographic ingredients for privacy-preserving
applications such as anonymous credentials, e-voting, and Bitcoin. Despite the great variety …

Group signatures are significant primitive for anonymity, which allow group members to sign
messages while hiding in the group, however, the signers remain accountable. Most of the …

Anonymity networks, such as the Tor network, are highly decentralized and make heavy use
of ephemeral identities. Both of these characteristics run in direct opposition to a traditional …

Blind signatures have numerous applications in privacy-preserving technologies. While
there exist many practical blind signatures from number-theoretic assumptions, the situation …
