FIELD: radio engineering and communications.
SUBSTANCE: invention relates to means of safe communication. In a network system for wireless communication, a participant accesses a network through a configurator. Participant retrieves the data template, which is a public network key, through an out-of-band channel through a sensor. Participant outputs first shared key based on network public key and first secret key of participant, and encodes a second public key of the participant using the first shared key, and generates a network access request. Configurator also outputs the first shared key and verifies whether the encoded second public key of the participant is encoded by the first shared key, and, if so, generates security data and cryptographically protects data using a second shared key and generates a network access message.
EFFECT: technical result consists in improvement of efficiency and safety of access to public wireless networks.
