A public-key threshold cryptosystem based on residue rings
Stephanie Deacon, Eduardo Duéñez, José Iovino · Journal of Discrete Mathematical Sciences and Cryptography · 2007
We present a generalization of Pedersen’s public-key threshold cryptosystem. Pedersen’s protocol relies on the field properties of ℤ p . We generalize the protocol so that the calculations can be performed in residue rings that are not necessarily fields. The protocol presented here is polynomial-time equivalent to Pedersen’s.
