Measurement Details
Ciphertexts employ dense encoding with ring degree 216, meaning each ciphertext encodes 215 complex slots
Bootstrap maintains 19-bit precision, measured in terms of the infinite norm of the message-side error.
The performance is achieved with RLWE modulus ~21730, ring degree 216, and Hamming weight 1024, providing 128-bit security.
