Modulo Reduction for Paillier Encryptions and Application to Secure Statistical Analysis
Abstract. For the homomorphic Paillier cryptosystem we construct a protocol for secure modulo reduction, that on input of an encryption x with x of bit length x and a public ‘mod...

Oracle Separation in the Non-uniform Model
Abstract. Oracle separation methods are used in cryptography to rule out blackbox reductions between cryptographic primitives. It is sufficient to find an oracle relative to whic...
