Webpk(m): For the public key pk and a message vector m, HEAAN encrypts the message m into a ciphertext ct. 2. Dec sk(ct): Using the secret key, this algorithm returns the message vector encrypted by the ciphertext ct. 3. Add(ct1, ct2): This operation returns a new ciphertext that encrypts the message Dec sk(ct1) Dec sk(ct2). 4. WebMar 10, 2024 · The size of the message contained in a ciphertext increases exponentially as the ciphertext is multiplied repeatedly. To prevent the explosion of message size, HEAAN performs rescaling after each HE Mul by dividing the coefficients of the output ciphertext by p. Then the size of q, the ciphertext modulus, is adjusted to q ′ where log … WebOct 1, 2024 · By default, HEAAN inserts public evaluation keys for power-of-2 left and right rotations, and all rotations are performed using a combination of power-of-2 rotations. The ciphertext size is N / 2, so HEAAN stores 2 l o g (N) − 2 rotation keys by default.
