Authentication of wireless device entity

A method in a first network node for enabling trusted communication between a wireless device entity and a second network node via the first network node, wherein the first network node and a wireless device are adapted to communicate using a secure communication channel, the method comprising:

• receiving a message from the wireless device using the secure communication channel, wherein the message comprises information indicating that the wireless device entity is comprised in a trusted zone of the wireless device, wherein the trusted zone is at least partly trusted by the first network node;
• and
• determining that communication from the wireless device entity can be trusted since it has received the information indicating that the wireless device entity is comprised in the trusted zone of the wireless device.

A wireless device adapted to enable trusted communication between a wireless device entity and a second network node via a first network node, wherein the wireless device and the first network node are adapted to communicate using a secure communication channel, the wireless device comprising:

• a transmitter adapted to transmit a message to the first network node using the secure communication channel, wherein the message comprises information indicating that the wireless device entity is comprised in a trusted zone of the wireless device, wherein the trusted zone is at least partly trusted by the first network node.

A first network node adapted to enable trusted communication between a wireless device entity and a second network node via the first network node, wherein the first network node and a wireless device are adapted to communicate using a secure communication channel, the first network node comprising:

• a receiver adapted to receive a message from the wireless device using the secure communication channel, wherein the message comprises information indicating that the wireless device entity is comprised in a trusted zone of the wireless device, wherein the trusted zone is at least partly trusted by the first network node;
• and
• a determining unit adapted to determine that communication from the wireless device entity can be trusted since it has received the information indicating that the wireless device entity is comprised in the trusted zone of the wireless device.
