Paillier's cryptosystem revisited
WebAt Eurocrypt ’02, Cramer and Shoup introduced the idea of public key encryption schemes with double decryption mechanism (DD-PKE) and at Asiacrypt ’03, Bresson, Catalano and Pointcheval revisited the notion of DD-PKE. They proposed the first DD-PKE scheme (called BCP cryptosystem) over the group of quadratic residues. WebJan 1, 2002 · Abstract. Choi et al. proposed the modified Paillier cryptosystem (M-Paillier cryptosystem). They use a special public-key g ∈ ℤ/nℤ such that g ϕ(n) = 1 + n mod n 2, …

However, unlike many other … WebThe Paillier cryptosystem is an additive homomorphic cryptosystem, mean-ing that one can combine ciphertexts into a new ciphertext that is the encryp-tion of the sum of the messages of the original ciphertexts. The cryptosystem uses arithmetic over the groupZ∗ n2 and the cryptosystem can encrypt messages from the group Z n.
