Stronger Security for Blind Signatures with Attributes↗ (원문, 새 창)

본문 미리보기

Single-use anonymous credentials are issued once and allow users to unlinkably authenticate exactly once. Recent anonymous-token and age-verification systems increasingly rely on such credentials to minimize credential reuse and simplify revocation. These systems are typically instantiated from blind signatures, yielding lightweight credentials whose presentation reduces essentially to signature verification. Many deployments additionally require embedded attributes and selective attribute discl
