Improving the Efficiency of Cryptographic Data Management by Using an Adaptive Method of Planning Tomasz Czajka, Wojciech Oszywa, Michał Gawroński, Rafał Gliwa Cryptology Department, Military Communication Institute, Zegrze, Poland, {t.czajka, w.oszywa, m.gawronski, r.gliwa}@wil.waw.pl Abstract: The Electronic Cryptographic Data Management System (ECDMS) is designed for secure and correct preparation of cryptographic data. The process of preparation consists of three stages generally: planning of secure connections, generation of required keys and distribution of produced data to points of exploitation. These steps have to be perform sequentially. The planning can be realized by “according to needs” or “each to each” method. First method is inconvenient in use while second one extends time of data generation significantly. However the distribution process takes still the most of time. Till now distribution was realized by couriers. Nowadays, thanks to available secure telecommunication infrastructure, distribution can be realized in electronic way. A replacement of courier distribution with electronic one enables to improve efficiency and flexibility of ECDMS. Time of delivery data to devices is negligibly short and, in consequence, processes of planning and generation became a bottle neck in this case. In the article we will prove that in extreme situations method “according to needs” is impracticable and use of “each to each” method causes that time of data generation is unacceptably long. In answer to these difficulties we propose new method of secure connections planning called adaptive method. It combines advantages of two previous methods and eliminates disadvantages. One, crucial requirement for using this method is availability of communication infrastructure that will allow ECDMS to monitor work of supported devices. Keywords: Cryptographic data management, key generation, adaptive method I. Introduction A correct operation of data protection systems depends on an appropriate preparation of cryptographic data. There are special dedicated systems, called Electronic Cryptographic Data Management Systems (ECDMS), which are responsible for realization of this goal. An example of such system is commonly known American EKMS i.e. Electronic Key Management System. The specific tasks of the ECDMS can be very different and depend on the requirements of the concrete data protection system. Additionally, development of data protection systems implies the need of increasing an efficiency of ECDMS.
