generateRandomRinZn

public BigInteger generateRandomRinZn(SecureRandom random)

This method generates a random r in Z_{n}^* for each separate encryption using the same modulus n Paillier cryptosystem allows the generated r to differ every time, such that the same plaintext encrypted several times will produce different ciphertext every time.

参数:

random - SecureRandom

返回:

r
