摘要： According to various embodiments, a cellular architecture for enhanced privacy regarding identity and location of a computing device is disclosed. The architecture includes a privacy gateway connected to the core packet forwarding gateway, where the privacy gateway is configured to authenticate the computing device while hiding the identity of the computing device by verifying authentication tokens that represent units of access. The architecture further includes an over-the-air (OTA) gateway configured to select an international mobile subscriber identity (IMSI) from a pool of valid IMSIs and deliver the selected IMSI to a subscriber identity module (SIM) card of the computing device, where the SIM card periodically shuffles the pool of valid IMSIs.
