Implementing HE
To implement HE, choose a suitable HE library from those outlined previously. Make sure your choice is appropriate based on your specific use case, then perform the following steps:
- Generate the public and private keys required for the encryption scheme.
- Convert the plaintext data that needs to be encrypted into a suitable format for the encryption scheme, such as a polynomial.
- Encrypt the plaintext data using the public key generated in step 2.
- Perform the homomorphic operations on the ciphertext data without decrypting it.
- Decrypt the resulting ciphertext data using the private key generated in step 2 to obtain the result of the homomorphic operations on the plaintext data.
Implementing HE can be complex and requires expertise in cryptography and mathematics. It is important to ensure that the implementation is secure and efficient, as HE can be computationally intensive.
