Threshold digital signatures enable a distributed execution of signature functionalities and
will play a crucial role in the security of emerging decentralized next-generation networked …

Data are generated by Internet of Things (IoT) devices and centralized at a cloud server, that
can later be traded with third parties, ie, data marketing, to enable various data-intensive …

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

Secure cross-domain authorization and authentication (AA) enable application service
providers (ASPs) to allow users for resource access from different trusted domains. In this …

Attribute-based credential systems enable users to authenticate in a privacy-preserving
manner. However, in such schemes verifying a user's credential requires knowledge of the …

Existing threshold signature schemes come in two flavors:(i) fully private, where the
signature reveals nothing about the set of signers that generated the signature, and (ii) …

To solve the data island issue in the distributed Internet of Things (IoT) without privacy
leakage, privacy-preserving federated learning (PPFL) has been extensively explored in …

The increasing concern for identity confidentiality in the Smart City scenario has fostered
research on privacy-preserving authentication based on pseudonymization. Pseudonym …

In this paper, we propose a blockchain-based collaborative credential management scheme
for anonymous authentication in space-air-ground integrated vehicular networks (SAGVN) …

Abstract Structure-preserving signatures (SPS) are an important building block for privacy-
preserving cryptographic primitives, such as electronic cash, anonymous credentials, and …
