FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering for user authentication. Technical result is achieved by obtaining first cryptographic key; using first cryptographic key and plurality of restriction identifiers, in which limitation identifier of plurality of restriction identifiers indicates at least one of: identification information key zone from plurality of key zones, where said key can be used, geographic position, time or identity of a user, to obtain a second cryptographic key.
EFFECT: high efficiency of authenticating a user.
