Abstract: Along with the accelerated expanding/development of IT networks, there is an increase in the amount of information stocked, transmitted and processed in these networks, from both, public and private areas. The risk of losing such data may have a negative impact not only on people`s lives but on organizations` activity, particularly the governmental ones. That is why establishing actions intended to provide information security is an objective of high priority for military organizations and not only. For this category of information the security is provided by cryptographic algorithms which, in order to grant a high protection, must meet the principles identified by Shannon (1949): randomness, confusion and diffusion. This paper presents a method to verify the randomness by using a minimum suite of tests.
