Abstract: It is often necessary to securely transfer data, such as authenticators or authorization tokens, between programs running on the same end-user device. The teachings hereof enable the pairing of two programs executing on a given end-user device and then the transfer of data from one program to the other. In an embodiment, a first program connects to a server and sends encrypted data elements. A second program intercepts the connection and/or the encrypted data elements. The second program tunnels the encrypted data elements (which remain opaque to the second program at this point) to a server, using an encapsulating protocol. This enables the server to receive the data elements sent by the first program, decrypt them, and provide them to the second program via return message using control fields of the encapsulating protocol. Once set up, the tunneling arrangement enables bidirectional data transfer.
