Title:
Threshold Cryptosystems Based on 2^k-th Power Residue Symbols

Authors: George Teseleanu

Abstract:

In this paper we introduce a novel version of the Joye-Libert cryptosystem that allows users to decrypt without knowing the factorisation of the composite modulus. Then we use our construction as a building block for a threshold decryption protocol of the homomorphic Joye-Libert encryption scheme. Finally, we present several extensions of the threshold cryptosystem.
