Abstract: A method comprises: Sending, by a first Chip Interface Device (CID), to a second CID, using a CID type protocol, a request for establishing a secure channel over a wireless protocol. Sending, by the second CID, to a Personal Computer Smart Card (PCSC), a first request for establishing a connection to the chip. Establishing, by the PCSC, a connection to the chip. Establishing, by the PCSC, a connection to the second CID. Establishing, by the second CID, a secure session with the first CID by using a session key. And sending, by the second CID, to the first CID, while using the CID type protocol, a secure CID channel establishment success that allows sending or receiving APDU(s) via the established secure channel over the wireless protocol. The second CID renders apparent to the first CID the chip as being connected.

Abstract: The invention relates to a method for authenticating to a second device. A first device shares with the second device at least one session key. The first device sends to at least one third device at least one first session key. The at least one third device connects directly to the second device by using the at least one first session key. According to the invention, the method further comprises the following steps. The first device sends to the at least one third device a command for disconnecting from or switching to a non-connected mode with the second device. And the at least one third device disconnects from or switches to a non-connected mode with the second device based upon the received command. The invention also pertains to corresponding first device and system for authenticating to a second device.

Abstract: Method of joining at least two components (2, 3) utilising a fitting (1), where at least one of the components comprises, or is made of, a material which is difficult to weld. The components (2, 3) are provided with thicker walls at the end surfaces (6) that are to be joined. At least one of the thicker end walls is provided with an internal or external thread (T) and said at least two components are joined together by screwing said threaded end walls into and/or onto the fitting (1).
