EXTERNAL AUTHENTICATION SUPPORT VIA UNSECURED NETWORK Russian patent published in 2016 - IPC H04L29/06 H04L9/08 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method of supporting external authentication via an unsecured network, which includes generating a first authentication request for authenticating user equipment in a communication network which provides connectivity for the user equipment via an unsecured access network, wherein the authentication request is an authentication request of a key information exchange mechanism and contains authentication data; sending the first authentication request for authenticating the user equipment in the communication network based on the authentication data; generating, after authentication in the communication network, a second authentication request for authenticating the user equipment in a packet data network external to the communication network, and sending the second authentication request; wherein the first authentication request precedes a message sent between the user equipment and the communication network, indicating that serial multiple authentication is supported.

EFFECT: enabling transfer of user account data between user equipment, using unsecured access, and a backbone network.
