To guarantee the confidentiality of the participants with respect to each other and potential eavesdroppers, we use the zero-concentrated differential privacy notion (zCDP). Privacy is achieved by perturbing the outcome of the computation at each client with a variance-decreasing Gaussian noise. ZCDP allows for better accuracy than the conventional $(\\epsilon, \\delta)$-DP and stronger guarantees than the more recent R\\'enyi-DP by assuming adversaries aggregate all the exchanged messages.
