MODERNISATION OF TECHNOLOGY AND EDUCATIONS METHODS ORIENTATED TO AREA OF CRYPTOGRAPHY FOR SAFETY CRITICAL APPLICATIONS

Mária Franeková

Inseparable part of education orientated to safety is area of safety communications, which contents cryptography part too. Requisites of subjects development at technical universities in specialisation of Automation is result of request from praxes where in last decade was notified development of applications which used safety-related communication system (e. g. area of industrial applications, safety-related control and communications systems in railway or road applications). Pedagogical staff of Department of Control and Information Systems at University of Žilina has sufficient theoretical and practical knowing which can used within realisation of project KEGA orientated to modernisation of education methodology with using modern HW and SW cryptography tools. It is new perspective discipline based on using cryptography in applications with increasing safety integrity level (SIL) which needs transfer of knowledge of the newest e-learning technology of educations to educations process at home university and partner’s Todor Kableshov University too.

Cryptography techniques are became in the last several decade the generally assurance mechanisms within COTS (Commercial Off The Shelf) technologies but in the safety critical application they are recommended to use in the last years only. Selection of cryptography technique, modes of operation and methods related with key management system must be realized in consequence with the norm valid for safety related messages transmission.

Several part of cryptography systems are in phase of developing and concerning to very dynamic developing discipline from the area of cryptanalytic attacks several recommended cryptography mechanisms are inapplicable in EURORADIO protocol. This is why it is necessary considering the computational safety of cryptography mechanisms, consider their selection and design KMS (Key Management System) for these algorithms. Recently KMS for ETCS system in L2 in particular European countries in phase of development and decisions, whereby the selection of off - line or on - line KMS are solved and which principles of KMS will be supported (symmetric or asymmetric cryptography systems).

KMS solves without generation of keys additional important procedures of key manipulations (e.g. store, distribution, changing) whereby these procedures must be solved on the safety manner and control within the life time of cryptography system. The next question which will be solved in the future is question about CA (certification authority) for KMS within European countries for ETCS system. In considering of interoperability of railway transport in Europe these procedures and agreements must be the same and all questions must be solved uniform in EU countries with connection to states of near continents.
