We construct an efficient dynamic group signature (or more generally an accountable ring
signature) from isogeny and lattice assumptions. Our group signature is based on a simple …

Vehicular ad-hoc networks (VANETs) have drawn a lot of attention for their potential to
improve traffic efficiency and safety. To deal with anonymous authentication and message …

Both ring signatures and group signatures are useful privacy tools, allowing signers to hide
their identities within a set of other public keys, while allowing their signatures to be …

Ring signatures are significant cryptographic primitives used for anonymous authentication
due to their anonymity and spontaneity. However, in some scenarios, they may offer …

Cloud Computing has proved to be a boon for many individuals and organizations who
cannot afford infrastructure and maintenance cost of resources. But the untrusted nature of …

During the Coincheck incident, which recorded the largest damages in cryptocurrency
history in 2018, it was demonstrated that using Mosaic token can have a certain effect …

Ring signature and group signature are two major cryptographic primitives providing users
anonymity and authentication simultaneously. While both primitives enable any user to sign …

A zero-knowledge proof is a fundamental cryptographic primitive that enables the
verification of statements without revealing unnecessary information. Zero-knowledge proofs …

In most practical cloud computing applications such as e-voting, auctions, health, and
