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

Society appears to be on the verge of recognizing the need for control over sensitive data in
modern web applications. Recently, many systems claim to give control to individuals …

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 …

Let us assume that Alice has received a constant-size signature on a set of messages {m_i\}
_ i= 1^ n from some organization. Depending on the situation, Alice might need to disclose …

ZEBRA is an Anonymous Credential (AC) scheme, supporting auditability and revocation,
