Effective generation of cryptographic material for large hierarchical communication networks

In this paper, the problem of increasing the efficiency of cryptographic material generation for communication networks of large IT systems is presented. As it results from the conducted tests, it is possible to improve the performance of the cryptographic data generation several times, after multi-core/multi-process computer systems are applied and appropriate parallel cryptographic data generation system is designed. The IT network class described in the paper corresponds to, e.g. a system for the public administration purposes, where numerous IT relations between the system components within the superior-subordinate relationship are present.
