The Industrial Internet of Things (IIoT) that introduces Internet of Things (IoT) technology into
industrial environments is beneficial to construct smart factories. It utilizes various sensors to …

Digital signature is a fundamental primitive with numerous applications. Following the
development of pairing-based cryptography, several taking advantage of this setting have …

Anonymous credentials (ACs) are a powerful cryptographic tool for the secure use of digital
services, when simultaneously aiming for strong privacy guarantees of users combined with …

Anonymous credentials (AC) offer privacy in user-centric identity management. They enable
users to authenticate anonymously, revealing only necessary attributes. With the rise of …

Abstract Structure-preserving signatures (SPS) are a powerful building block for
cryptographic protocols. We introduce SPS on equivalence classes (SPS-EQ), which allow …

Anonymous attribute-based credentials (ABCs) are a powerful tool allowing users to
authenticate while maintaining privacy. When instantiated from structure-preserving …

It takes time for theoretical advances to get used in practical schemes. Anonymous
credential schemes are no exception. For instance, existing schemes suited for real-world …

Anonymous credentials are a powerful tool for making assertions about identity while
maintaining privacy and have been the subject of study for many years. The interest in …

Round-optimal blind signatures are notoriously hard to construct in the standard model,
especially in the malicious-signer model, where blindness must hold under adversarially …

Equivalence class signatures (EQS; Asiacrypt'14), sign vectors of elements from a bilinear
group. Anyone can transform a signature on a vector to a signature on any multiple of that …
