Example #1: Homomorphic Arithmetic Over 3-bit integers

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
