Abstract

As not only the amount of data stored digitally in computers but our dependency of these data, too, increases day by day it is of critical importance to prevent unathorized data accesses. To gain access to other parties' data and, on the other hand, make it as hard as possible is (and has always been) a heavy fight between the data owners and the spies, only the tools have changed since ancient times. Https has become part of our everyday life as an excellent arm to protect the sensitive data of confidential communications from accessing our gmail mailbox to netbanking. Https is based on a two-key encryption standard which, according to the publicly known results of mathematics, cannot be attacked directly. In theory. In practice there exist roundabouts. In this paper I show a possible and low cost technical-organisational solution of such an attack which could be performed because of some malpractice of IT-managers: manipulation of top level certificates.
