FIELD: information technologies.
SUBSTANCE: two stages of authentication are carried out: initial stage of the first contact (authentication according to principle of Authentication, Authorisation, Accounting, AAA), and "light" stage, when repeatedly the key material is used, generated in process of the first contact. An authenticator of a cell within the network generates temporary keys used for coding by means of a requesting point in a cell through four-stage handshake and organisation of feedback with a keys distributor, and a keys distributor is realised by AAA-client, which generates keys used to authenticate the cell point during the first contact or fast association of safety.
EFFECT: higher speed of establishing secured communication lines between the cell units.
