In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...

Abstract. In this paper, we examine issues related to the construction of identity-based threshold decryption schemes and argue that it is important in practice to design an identi...

This paper improves the Finiasz-Vaudenay construction of TCHo, a hardware-oriented public-key cryptosystem, whose security relies on the hardness of finding a low-weight multiple ...

We describe a short signature scheme that is strongly existentially unforgeable under an adaptive chosen message attack in the standard security model. Our construction works in g...
