Abstract
The paper deal with problems of data security in the safety - related transmission systems defined within railway process. In details is analysed possibility od using hash-coding techniques, which are generally defined in norm EN 50159-2. According to specification of transmission in railway applications the type of secure hash keying and nonkeyng techniques are recommended. There are discussed the results of experimental part, which are related to the comparison of time relation of hash code determination.
