Abstract:
The embodiments set forth techniques for an embedded Universal Integrated Circuit Card (eUICC) to conditionally require, when performing management operations in association with electronic Subscriber Identity Modules (eSIMs), human-based authentication. The eUICC receives a request to perform a management operation in association with an eSIM. In response, the eUICC determines whether a policy being enforced by the eUICC indicates that a human-based authentication is required prior to performing the management operation. Next, the eUICC causes the mobile device to prompt a user of the mobile device to carry out the human-based authentication. The management operation is then performed or ignored in accordance with results of the human-based authentication.
Abstract:
Methods and apparatus for user authentication and human intent verification of administrative operations for eSIMs of an eUICC included in a mobile device are disclosed. Certain administrative operations, such as import, modification, and/or export, of an eSEVI and/or for an eUICCs firmware can require user authentication and/or human intent verification before execution of the administrative operations are performed or completed by the mobile device. A user of the mobile device provides information to link an external user account to an eSEVI upon (or subsequent to) installation on the eUICC. User credentials, such as a user name and password, and/or information generated therefrom, can be used to authenticate the user with an external server. In response to successful user authentication, the administrative operations are performed. Human intent verification can also be performed in conjunction with user authentication to prevent malware from interfering with eSIM and/or eUICC functions of the mobile device.
Abstract:
A method for establishing a secure communication channel between an off-card entity and an electronic Universal Integrated Circuit Card (eUICC) is provided. The method involves establishing symmetric keys that are ephemeral in scope. Specifically, an off-card entity, and each eUICC in a set of eUICCs managed by the off-card entity, possess long-term Public Key Infrastructure (PKI) information. When a secure communication channel is to be established between the off-card entity and an eUICC, the eUICC and the off-card entity can authenticate one another in accordance with the respectively-possessed PKI information (e.g., verifying public keys). After authentication, the off-card entity and the eUICC establish a shared session-based symmetric key for implementing the secure communication channel. Specifically, the shared session-based symmetric key is generated according to whether perfect or half forward security is desired. Once the shared session-based symmetric key is established, the off-card entity and the eUICC can securely communicate information.
Abstract:
Methods and apparatus for the deployment of financial instruments and other assets are disclosed. In one embodiment, a security software protocol is disclosed that guarantees that the asset is always securely encrypted, that one and only one copy of an asset exists, and the asset is delivered to an authenticated and/or authorized customer. Additionally, exemplary embodiments of provisioning systems are disclosed that are capable of, among other things, handling large bursts of traffic (such as can occur on a so-called "launch day" of a device).
Abstract:
Apparatus and methods for managing and sharing data across multiple access control clients in devices are disclosed herein. In one embodiment, the access control clients comprise electronic Subscriber Identity Modules (eSIMs) disposed on an embedded Universal Integrated Circuit Card (eUICC). Each eSIM contains its own data. An Advanced Subscriber Identity Toolkit application maintained within the eUICC facilitates managing and sharing multiple eSIMs' data for various purposes such as sharing phonebook contacts or facilitating automatic switch-over between the multiple eSIMs (such as based on user context).
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.
Abstract:
A method for preparing an eSIM for provisioning is provided. The method can include a provisioning server encrypting the eSIM with a symmetric key. The method can further include the provisioning server, after determining a target eUICC to which the eSIM is to be provisioned, encrypting the symmetric key with a key encryption key derived based at least in part on a private key associated with the provisioning server and a public key associated with the target eUICC. The method can additionally include the provisioning server formatting an eSIM package including the encrypted eSIM, the encrypted symmetric key, and a public key corresponding to the private key associated with the provisioning server. The method can also include the provisioning server sending the eSIM package to the target eUICC.

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.
