Abstract. Sanitizable signatures, introduced by Ateniese et al. at ESORICS’05, allow to issue a signature on a message where certain predefined message blocks may later be chang...
We present a privacy-assured multiplication protocol using which an arbitrary arithmetic formula with inputs from two parties over a finite field Fp can be jointly computed on en...
Functional encryption (FE) enables sophisticated control over decryption rights in a multi-user scenario, while functional signature (FS) allows to enforce complex constraints on s...
Abstract. We give a simple and efficient construction of unique signature on groups equipped with bilinear map. In contrast to prior works, our proof of security is based on comput...
