1. A computer-executable method for privacy-preserving aggregation of encrypted data, comprising:

  • distributing secret keys to a plurality of devices;

    receiving at least a pair of encrypted vectors from each device of a subset of the plurality of devices, wherein one of the encrypted vectors is associated with a set of numerical values and the other encrypted vector is associated with corresponding square values of the set of numerical values, each pair of encrypted vectors encrypted using a respective secret key distributed to a device of the plurality of devices;

    computing, for each pair of encrypted vector elements associated with a numerical value and a square of the numerical value, a mean and variance of a probability density function; and

    generating a plurality of probability density functions based on the computed mean and variance values.
