The github project called demo_z8z is using Concrete to implement exact homomorphic computation with 3-bit integers encrypted in LWE ciphertexts.

The following functions are implemented:

addition between a ciphertext and a constant

subtraction between a ciphertext and a constant

multiplication between a ciphertext and a constant

addition between two ciphertexts

subtraction between two ciphertexts

multiplication between two ciphertexts

max between two ciphertexts
