Title: CONNECTION APPARATUS FOR ESTABLISHING A SECURED APPLICATION-LEVEL COMMUNICATION CONNECTION
Abstract:
The invention relates to a Connection apparatus (102, 202, 502), in particular, a connection server (102, 202, 502), for establishing a secured application-level communication connection between at least one first device (104, 204.1, 204.2, 504) and at least one second device (106, 206, 506), the connection apparatus (102, 202, 502) comprising at least one connection controlling module (108, 208, 508.1, 508.2) configured to initiate transmitting of at least one second request message comprising at least one communication data set with at least one connection key to the second device (106, 206, 506) upon receipt of at least one first request message from the first device (104, 204.1, 204.2, 506) for establishing the secured application-level communication connection, wherein the connection controlling module (108, 208, 508.1, 508.2) is configured to check the connection key used for establishing at least one second tunnel communication connection (112, 212, 512) between the connection apparatus (102, 202, 502) and the second device (106, 206, 506) at least based on the transmitted connection key, wherein the connection controlling module (108, 208, 508.1, 508.2) is configured to establish the a tunnel communication connection by pairing at least a first tunnel communication connection (110, 210.1, 210.2, 510) established between the first device (104, 204.1, 204.2, 504) and the connection apparatus (102, 202, 502) with the second tunnel communication connection (112, 212, 512) based on the check result, and wherein the tunnel connection is established such that the secured application-level communication connection can be established over the established tunnel communication connection.
