Abstract
A user equipment (UE) performs a method for determining an address of a first network node Trusted Non-3GPP Gateway Function. The UE receives from the first network node, a protected address of the first network node. The UE unprotects the protected address of the first network node, verifies an integrity of the address of the first network node based on the key associated with the first network node or decrypts the protected address of the first network node, and it initiates a security protocol with the first network node based on the address of the first network node.
Claims25
A method performed by a user equipment device, UE, for determining an address of a first network node the method comprising:
- receiving from the first network node, a protected address of the first network node, wherein the protected address of the first network node is protected based on a key associated with the first network node;
- unprotecting the protected address of the first network node based on the key associated with the first network node to determine an address of the first network node, wherein unprotecting the protected address comprises at least one of:
- verifying an integrity of the address of the first network node based on the key associated with the first network node;
- or
- decrypting the protected address of the first network node based on the key associated with the first network node, wherein decrypting the protected address of the first network node results in the address of the first network node;
- and
- initiating a security protocol with the first network node based on the address of the first network node.
(canceled)
A user equipment device, UE, that determines an address of a first network node the UE comprising processing circuitry to perform operations, the operations comprising:
- receiving from the first network node, a protected address of the first network node, wherein the protected address of the first network node is protected based on a key associated with the first network node;
- unprotecting the protected address of the first network node based on the key associated with the first network node to determine an address of the TNGG, wherein unprotecting the protected address comprises at least one of:
- verifying an integrity of the address of the first network node based on the key associated with the first network node;
- or
- decrypting the protected address of the first network node based on the key associated with the first network node, wherein decrypting the protected address of the first network node results in the address of the first network node;
- and
- initiating a security protocol with the first network node based on the address of the first network node
(canceled)
A method performed by a first network node, for protecting an address of a first network node the method comprising:
- providing, to a user equipment device, UE, a protected address of the first network node, wherein the protected address of the first network node is protected based on a key associated with the UE;
- and
- receiving, from the UE, a request to initiate a security protocol.
A first network node of a Trusted Non-3GPP Access Network, TNAN, for protecting an address of the first network node, comprising processing circuitry to perform operations, the operations comprising:
- providing, to a User Equipment device, UE, a protected address of the first network node, wherein the protected address of the first network node is protected based on a key associated with the first network node and
- receiving, from the UE, a request to initiate a security protocol.
