密文计算

为满足数据使用过程的数据安全，在密文上实现基础计算就变的不可或缺。同态加密以其独特的数学性质，可以实现数据在同态加密之后，同态密文数据与明文具备完全一致的计算能力。也就是说，同态密文数据在需求方进行应用的时候不需要进行解密，可以直接对同态密文数据进行计算使用。当前支持的算子如下：同态加法。同态减法。同态乘法。同态除法。

To ensure data security during data utilization, implementing basic computations over ciphertext has become indispensable. Homomorphic encryption, with its unique mathematical properties, enables homomorphic ciphertext data to possess exactly the same computational capabilities as plaintext data after the original data is encrypted via homomorphic encryption. In other words, when the requesting party uses the homomorphic ciphertext data, there is no need to decrypt it; computations can be directly performed on the ciphertext. The currently supported operators are as follows: homomorphic addition, homomorphic subtraction, homomorphic multiplication, and homomorphic division.
