FIELD: information technology.
SUBSTANCE: disclosed method for "own-alien" recognition employs a protocol wherein a respondent first calculates its true and noisy status and then, after receiving from an interrogator question in the form of a random number, determines three answers to said question, and then transmits all calculated values to the interrogator which then verifies the legitimacy of the respondent by performing corresponding calculations and comparing results thereof with the noisy status of the respondent.
EFFECT: high mimic resistance owing to use of an authentication protocol based on zero-knowledge proof.
