Claim 0:
1. A method for differential privacy composition determination in secure computation and communication of a dataset, the method comprising:
determining a differential privacy configuration that includes a first privacy parameter and a second privacy parameter;
determining a privacy loss distribution;
providing a number of composition operations K;
performing a K-fold convolution operation of the privacy loss distribution by:
performing a two-fold convolution operation of the privacy loss distribution using a hash map based on the privacy loss distribution, and
performing a two-fold convolution operation of an intermediate convolution result using the hash map when K is greater than two;

determining a third privacy parameter and a fourth privacy parameter for a differential privacy composition based on the differential privacy configuration, the privacy loss distribution, the number of composition operations, and a result of the K-fold convolution operation; and
controlling the dataset based on at least one of the third privacy parameter and the fourth privacy parameter to limit access to the dataset.
