Annotation: Hardware (not software) effective cryptographic algorithm for mark formation of the data transmission beginning. A modification of the algorithm, which allows the data transmitting in the form of errors specially built-in marker, is suggested. It is shown that the problem, on which the algorithm cryptographic firmness is based, does not belong to NP class. The estimation of a number of operations needed for finding a key is given for the best (in the viewpoint of an attacker) case.

Keywords: master-key, marker, cryptographic firmness, memoryless automaton
