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 ...
We present the hash-based signature scheme XMSS. It is the first provably (forward) secure and practical signature scheme with minimal security requirements: a pseudorandom and a ...
We provide a positive result about the Fiat-Shamir (FS) transform in the standard model, showing how to use it to convert threemove identification protocols into two-tier signatur...
The Fiat-Shamir (FS) transform is a popular tool to produce particularly efficient digital signature schemes out of identification protocols. It is known that the resulting signat...
We introduce the notion of sanitizable signatures that offer many attractive security features for certain current and emerging applications. A sanitizable signature allows author...
