Abstract
Various embodiments relate to a method of encrypting a message m using a Paillier cryptosystem, including: computing a ciphertext c based upon the message m, N, and r, where N is the product of two distinct primes p and q, and r is randomly chosen such that r∈[1, N); computing a first verification value based upon u and N, where u is randomly chosen such that u∈[1, N); computing a second verification value s based upon u, r, the ciphertext c, the verification value, and a hash function H.
