Abstract
We study how to reduce the local computational cost associated with performing exponentiation. This involves transforming a large computational task into a large set of small computational tasks that are to be performed by a set of external servers who may all be controlled by one and the same adversary. In order to attack our problem, we introduce and employ the three principles of duplication, distribution and delegation. We apply our exponentiation scheme to performing inexpensive server-aided batch signature generation, and show noticeable efficiency improvements for batches of size 20 and up.
