HEhub同態(tài)加密庫

HEhub 是首個由國內開源的同態(tài)加密庫，可以實現(xiàn)在密文基礎上進行加、乘等基礎運算，并得到與明文相同的結果，從而實現(xiàn)數據可用不可見的目標。同態(tài)庫是隱私計算領域基礎的加密庫。

使用示例：

#include "fhe/ckks/ckks.h"
#include <cmath>
#include <iostream>

using namespace hehub;

int main() {
    int precision_bits = 30;
    auto params = ckks::create_params(4096, precision_bits);
    CkksSk sk(params);
    auto relin_key = get_relin_key(sk, params.additional_mod);

    CkksCt ct_sum;
    for (int i = 1; i <= 100000; i++) {
        auto pt = ckks::encode(1.0 / i, params);
        auto ct = ckks::encrypt(pt, sk);
        auto ct_squared = ckks::mult(ct, ct, relin_key);

        if (i == 1) {
            ct_sum = ct_squared;
        } else {
            ct_sum = ckks::add(ct_sum, ct_squared);
        }
    }

    double sum = ckks::decode(ckks::decrypt(ct_sum, sk));
    std::cout << "(" << sum << ", " << M_PI * M_PI / 6 << ")" << std::endl;
}
