square

Engine.sqaure(ciphertext, relinearization_key)

Returns the square of the input ciphertext.

• Input:
  • Ciphertext
  • RelinearizationKey, optional
    • If provided, the resulting ciphertext undergoes relinearization. This is recommended to facilitate subsequent operations.
• Output:
  • Ciphertext

Examples

from desilofhe import Engine

engine = Engine()
secret_key = engine.create_secret_key()
public_key = engine.create_public_key(secret_key)
relinearization_key = engine.create_relinearization_key(secret_key)

message = [1, 2, 3]
ciphertext = engine.encrypt(message, public_key)

squared = engine.square(ciphertext, relinearization_key)
