Abstract
We present a cryptanalysis of an encryption scheme based on Laplace Transforms proposed by A.P. Hiwarekar. We have shown that scheme is described in a superfluous manner. We have given equivalent operations for the scheme by means of which the scheme can be described in much simpler terms. Using these operations we can break the scheme in much lesser number of trials than that is claimed by the author. We have also given an example to illustrate our cryptanalytic attack in support of our findings.
