Methods and Devices Having a Key Distributor Function for Improving the Speed and Quality of a Handover

A key distributor node for a mesh network, comprising:

• a) a memory device with at least one first key, said first key derived from a master key for a plurality of terminals incorporated into a mesh network,
• b) at least one data communication device exchanging data with first and second access nodes for a terminal integrated wirelessly into the network,
• c) at least one processor connected to the memory device and the data communication device,
• wherein functions are provided for at least one processor that authenticates of the terminal at the second access node in response to a received key request from the second access node;
• d) a second key, to be derived from the first key stored in the memory device, and
• e) triggered transmission of the second key through the data communication device to the second access node,
• wherein the key distributor node has connections to the mesh network's first and second access nodes with security relationships that are established when the key request is received by the second access node, when using the first key.
