Heaan ciphertext size
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 … WebMar 10, 2024 · A critical shortcoming of HE is the high computation complexity of ciphertext arithmetic; especially, HE multiplication (HE Mul) is more than 10,000 times slower than …

Webcalled Single Instruction Multiple Data (aka SIMD) to encrypt multiple values into a single ciphertext. Another great progress in terms of machine learning applications is the rescalingprocedure [7], which can manage the magnitude of plaintext effectively.

The ciphertext size is N / 2, so HEAAN stores 2 l o g (N) − 2 rotation keys by default. The rotation keys consume significant memory, so this is trade-off between space and ...
