Method of maintaining safe state of safety systems with complex security, especially on railway, when making data impressions

摘要

Method of maintaining safe state security systems are composed of security, notably rail, when creating data imprinting, where at least two units together create fingerprint data, applying none of them alone, they do not create such a data fingerprint. The invention is characterized in that the process create fingerprint data is decomposed into a sequence of creating partial fingerprint data in a specified time sequence, the result is the original fingerprint data, and in the case where a fault is detected in any of the cooperating units, refuses intact unit that collaborates with impaired unit, creating a partial fingerprint data.
