    Abstract: Disclosed herein are different techniques for enabling a mobile device to dynamically support different authentication algorithms. A first technique involves configuring an eUICC included in the mobile device to implement various authentication algorithms that are utilized by MNOs (e.g., MNOs with which the mobile device can interact). Specifically, this technique involves the eUICC storing executable code for each of the various authentication algorithms. According to this technique, the eUICC is configured to manage at least one eSIM, where the eSIM includes (i) an identifier that corresponds to one of the various authentication algorithms implemented by the eUICC, and (ii) authentication parameters that are compatible with the authentication algorithm. A second technique involves configuring the eUICC to interface with an eSIM to extract (i) executable code for an authentication algorithm used by an MNO that corresponds to the eSIM, and (ii) authentication parameters that are compatible with the authentication algorithm.

    Abstract: Secure reception of a certificate revocation list (CRL) is determined. In some embodiments, a device initiates a CRL update by sending a message with a timestamp to an embedded universal integrated circuit card (eUICC). The eUICC generates a session identifier, nonce, or random number and builds a payload including an internal time value based on a server time, and an internal time value based on a past message received from the device. The eUICC cryptographically signs over the payload and sends it to the device. The device obtains a CRL from a host server, checks the CRL, and, if the CRL passes the device check, sends it to the eUICC along with a second device timestamp and the nonce. The eUICC then performs checks based on the timestamps, the nonce, the CRL and the internal time values to determine whether the CRL has been securely received.

    Abstract: Representative embodiments described herein set forth techniques for optimizing large-scale deliveries of electronic Subscriber Identity Modules (eSIMs) to mobile devices. Specifically, instead of generating and assigning eSIMs when mobile devices are being activated—which can require significant processing overhead—eSIMs are pre-generated with a basic set of information, and are later-assigned to the mobile devices when they are activated. This can provide considerable benefits over conventional approaches that involve generating and assigning eSIMs during mobile device activation, especially when new mobile devices (e.g., smartphones, tablets, etc.) are being launched and a large number of eSIM assignment requests are to be fulfilled in an efficient manner.
