Abstract: Embodiments described herein relate to eligibility checking for transfer of one or more electronic subscriber identity modules (eSIMs) between two mobile wireless devices. Eligibility to transfer an eSIM to an eUICC of a target device can depend on whether the eUICC of the target device satisfies certain security requirements for the eSIMs to be transferred. The mobile wireless devices can obtain a transfer eligibility result based on communication with one or more network-based servers that can determine compatibility for eSIM transfer.

Abstract: Duplicate processing of events registered at a root server is avoided. An electronic subscriber identity module (eSIM) server pushes, to a root server, data in the form of notification data portions indicating that commands or events need to be processed by a device. The device includes an embedded universal integrated circuit card (eUICC). The device pulls a notification list from the root server. The notification list includes one or more notification data portions. The device checks a given notification data portion to see if it represents a duplicate before communicating with the eSIM server to perform further processing related to the event. The device bases the check for duplication on an event history and/or on a hash value where the hash value is based on one or more eSIMs installed in the eUICC. The device is able to prioritize notification data portions before processing them.

Abstract: Embodiments provided herein identify a certificate issuer (CI) to be relied on as a trusted third party by an electronic subscriber identity module (eSIM) server in remote SIM provisioning (RSP) transactions with an embedded universal integrated circuit card (eUICC). In an RSP ecosystem, multiple CIs may exist. Parties rely on public key infrastructure (PKI) techniques for establishment of trust. Trust may be established based on a trusted third party such as a CI. Parties need to agree on the CI in order for some PKI techniques to be useful. Embodiments provided herein describe approaches for an eUICC and an eSIM server to arrive at an agreed-on CI. Candidate or negotiated CIs may be indicated on a public key identifier (PKID) list. A PKID list is distributed, in some embodiments, by means of a discovery server, via an activation code (AC) and/or during the establishment of a profile provisioning session.

Abstract: Disclosed herein is a technique for revoking a root certificate from at least one client device. In particular, the technique involves causing a secure element—which is included in the at least one client device and is configured to store the root certificate as well as at least one backup root certificate—to permanently disregard the root certificate and prevent the at least one client device from utilizing the specific root certificate. According to one embodiment, this revocation occurs in response to a receiving a revocation message that directly targets the root certificate, where the message includes at least two levels of authentication that are verified by the secure element prior to carrying out the revocation. Once the root certificate is revoked, the secure element can continue to utilize the at least one backup root certificate, while permanently disregarding the revoked root certificate.
