In this paper, we propose a new approach for constructing selectively convertible undeniable signature schemes, and present two efficient schemes based on RSA. Our approach allows ...
Digital signature systems provide a way to transfer trust from the public key to the signed data; this is used extensively within PKIs. However, some applications need a transfer o...
Abstract. Known compact e-cash schemes are constructed from signature schemes with efficient protocols and verifiable random functions. In this paper, we introduce a different ap...
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
Abstract. We show that the Winternitz one-time signature scheme is existentially unforgeable under adaptive chosen message attacks when instantiated with a family of pseudo random ...
