Abstract
A mechanism is provided for establishing a shared secret-key for secure communication between nodes in a wireless network. A first node in the wireless network provides a spreading code to a second node of the wireless network. The second node provides a first input for the key establishment to the first node using communication encoded with the spreading code. Responsive to obtaining the first input from the second node, the first node provides a second input for the key establishment to the second node using communication encoded with the spreading code. Then, the first node and the second node establish the shared secret-key using the first input and the second input.
