Homomorphic encryption method and application thereof in privacy protection classifier
A homomorphic encryption and encryption system technology, applied in digital data protection, instruments, machine learning, etc., can solve problems such as excessive calculation overhead, inability to batch multiplication or addition, and Bayesian risk is not small enough to reduce errors. Effects of classification loss, reduced interaction rounds, and reduced Bayesian risk

Embodiment
[0042] Such as figure 1 As shown, the homomorphic encryption method of the present embodiment is to construct a homomorphic encryption tool on the basis of the Paillier encryption system:
[0043] MASE = (KeyGen, Enc, Dec-int, Dec, Mul, Add),
[0044] Specific steps are as follows:
[0045] S1. Both the sender and receiver of the message use the KeyGen algorithm to generate the public key pk and private key sk;
[0046] KeyGen is the security parameter κ∈N used in the Paillier encryption system and returns the probability algorithm of the public key / private key pair (pk, sk), recorded as: (pk, sk)←KeyGen(1 κ ), and pk=(n,g), sk=(λ,μ);
[0047] Among them, n=p*q, p and q are two different large prime numbers randomly selected; λ=lcm(p-1,q-1), lcm(·,·) is expressed as finding the least common multiple of two parameters ; g is a random number, satisfying means less than n 2 and with n 2 The set of coprime modulo n 2 A group of multiplication, m represents the integer for...
