Abstract
There is provided a technique of establishing encryption keys for communication between 1peer and 2peer via a data path. The technique comprises: by each peer, using input keying material to independently generate equivalent pairs of peer encryption keys (PEKs), verifying equivalence of the generated PEK pairs, and using by 1peer and 2peer the verified PEK pairs to become in possession of equivalent pairs of session encryption keys (SEKs). Verifying comprises: generating by 1peer a first handshake (HS) message encrypted by PEK Tx1 and sending the first HS message to the 2peer via the data path; decrypting by the 2peer the first HS message using the PEK Rx2, generating a second HS message encrypted by PEK Tx2, and sending the second HS message to the 1peer via the data path; and decrypting the second HS message by the 1peer using PEK Rx1.
