- There have been partial homomorphic encryption schemes for quite a while, where a limited number of operations can be performed on encrypted data, for example only addition or only multiplication.
- addition of two ciphertexts
- multiplication of a ciphertext by a plaintext number
- When two ciphertexts are multiplied, the result decrypts to the sum of their plaintexts:
- When a ciphertext is raised to the power of a plaintext, the result decrypts to the product of the two plaintexts:
