Opis:: The analyses were aimed at determination of failure effects in the transmission system, which allow identifying the transition process of the system from a safety state (it may not be necessarily a failure - a free state) to a dangerous state and permit to calculate probability of the dangerous state occurrence of the system as a failure effect to the operating system. Dangerous states of the safety Fieldbus system are mainly caused by systematic failures within a specification of the system, electromagnetic interferences (EMI) and random failures of the HW effects. The effects of electromagnetic interferences and random failures of HW can be described in the paper by the use of time table.

Opis:: Paper deals with problems of KMS (Key Management System), which is developed in mobile communications GSM-R (Global System Mobile for Railway) recommended within the European Train Control System (ETCS), through the Euroradio system. Th e main part is oriented to safety procedures description of off-line KMS system between communication entities of ETCS system. In the experimental part the results of computational safety of modifi ed DES algorithm are summarised using special brute force attack to key – birthday paradox.

Opis:: The paper deals with assumptions for an open transmission in railway control applications ensuring the SIL4 safety integrity level. Using the public transmission standards, especially the wireless transmission (including radio access to Internet) requires the appropriate protection to ensure the data integrity (protection against fault and lost of transmission) and encoding (protection against unauthorized access). The estimated this way the THR values, even for single transmission channel does not differ for fault level of computer hardware in redundant structures. The theoretical results are compared with experimental tests of polish railway automation systems.
