Encrypt a real number under a Paillier public key — encrypt

Splits x into integer and fractional parts, encrypts each part as a separate PaillierCiphertext, and packages the result as a PaillierEncryptedReal so that later additions and subtractions can be performed via R's arithmetic operators.

Usage

encrypt_real(public_key, x, den)

Arguments

public_key: a PaillierPublicKey.
x: a real number.
den: the denominator used to scale the fractional part. The same denominator must be used at encryption and decryption.

Value

a PaillierEncryptedReal.
