Abstract:
The invention solves the way of authentication of secured data channel between two sides (A, B) when there is at first established a non-authenticated protected data channel (1), with ending (3) of the data channel (1) on the first side (A) and ending (4) of the data channel (1) on the other side (B) and with target application (7) on the first side (A) and target application (8) on the other side (B), while the endings (3) and (4) have a non-authenticated shared secret (5), consequently, on both sides (A, B) of the data channel (1) there are calculated the data derived from non-authenticated shared secret (5), then the data derived from the non-authenticated shared secret (5) are passed via external communication means out of the data channel (1) to two sides (11, 12) of the external authentication system (2), which consequently performs authentication of communicating sides (A, B) including authentication of the data channel (1).
