Abstract: Some embodiments are directed to a cryptographic encrypted computation method (400). The method involves performing a blind rotation of a ciphertext according to a test polynomial. The blind rotation results in an encrypted polynomial product of the test polynomial and a bootstrapping monomial represents the plaintext value as an exponent, modulo a modulus (q) and modulo a quotient polynomial (p(X)). . . . The quotient polynomial p(X) divides a number-theoretic transform (NTT) polynomial XM?1 that allows a number-theoretic transform modulo the modulus q, e.g., q is a power of two and p(X)=XN+XN/2+1. The blind rotation is performed using the NTT, while the test polynomial is defined in such a way that the polynomial product is programmed to have desired output values for respective plaintext values as a fixed coefficient.
