摘要

Secure, authenticated communication is enabled between an initiator (12) (e.g., a user equipment) and a responder (14) (e.g., an authentication server function, AUSF, or a subscription de-concealing function, SIDF). The initiator (12) transmits a message (20) to the responder (14) over a secure communication channel (16). The message (20) may include information indicating a third party (18) whose signing of data (e.g., bound to the secure communication channel (16)) will authenticate the responder (14) to the initiator (12). The responder (14) correspondingly retrieves from the third party (18) data that is signed by the third party (18) and transmits a response (24) to the initiator (12) that includes the retrieved data. The initiator (12) receives this response (24) and determines whether or not the responder (14) is authenticated by determining whether or not the response (24) includes data that is signed by the third party (18).

Further note that third party equipment of the third party 18 as described above may perform any of the processing herein by implementing any functional means or units. In one embodiment, for example, third party equipment comprises respective circuits or circuitry configured to perform the steps shown in FIG. 6. The circuits or circuitry in this regard may comprise circuits dedicated to performing certain functional processing and/or one or more microprocessors in conjunction with memory. In embodiments that employ memory, which may comprise one or several types of memory such as read-only memory (ROM), random-access memory, cache memory, flash memory devices, optical storage devices, etc., the memory stores program code that, when executed by the one or more processors, carries out the techniques described herein.

FIG. 9A illustrates third party equipment 800 of the third party 18 in accordance with one or more embodiments. As shown, the third party equipment 800 includes processing circuitry 810 and communication circuitry 820. The communication circuitry 820 is configured to transmit and/or receive information to and/or from one or more other nodes, e.g., via any communication technology. The processing circuitry 810 is configured to perform processing described above, e.g., in FIG. 6, such as by executing instructions stored in memory 830. The processing circuitry 810 in this regard may implement certain functional means, units, or modules.
