AUTHENTICATION OF SAFETY AND CONTROL OF KEYS IN INFRASTRUCTURAL WIRELESS MULTILINK NETWORK Russian patent published in 2010 - IPC H04L9/00 H04W12/00

Abstract RU 2407181 C1

FIELD: information technologies.

SUBSTANCE: in method of safety authentication in each link of wireless network, upper level key holder (R0KH) receives and stores upper pair main key (PMK_0) for each query wireless device after process of authentication. All access points (AP) of authenticator accept the role of the first level key holder (R1KH) and receive pair main key of another level (PMK_1) from R0KH. Key of data protection of the communication line level is extracted from PMK_1 by means of 4-side quitting of communication according to standard 802.11i.

EFFECT: provision of hierarchical safety structure for each link of wireless network.
