—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...
This paper presents an off-line divisible e-cash scheme where a user can withdraw a divisible coin of monetary value 2L that he can parceled and spend anonymously and unlinkably. ...
We give a short constant-size group signature scheme, which we prove fully secure under reasonable assumptions in bilinear groups, in the standard model. We achieve this result by ...
