We construct public-key cryptosystems that remain secure even when the adversary is given any computationally uninvertible function of the secret key as auxiliary input (even one t...
—Fault attacks constitute a major threat toward cryptographic products supporting RSA-based technologies. Most often, the public exponent is unknown, turning resistance to fault ...
A number of previous papers explored the notion of identity-based group signature. We present a generic construction of identity-based group signatures. Our construction is based o...
Abstract. Untraceability and unreuseability are essential security properties for electronic cash protocols. Many protocols have been proposed to meet these two properties. However...
