METHODS AND APPARATUS FOR LARGE SCALE DISTRIBUTION OF ELECTRONIC ACCESS CLIENTS

摘要

Methods and apparatus for large scale distribution of electronic access control clients. In one aspect, a tiered security software protocol is disclosed. In one exemplary embodiment, a server electronic Universal Integrated Circuit Card (eUICC) and client eUICC software comprise a so-called “stack” of software layers. Each software layer is responsible for a set of hierarchical functions which are negotiated with its corresponding peer software layer. The tiered security software protocol is configured for large scale distribution of electronic Subscriber Identity Modules (eSIMs).

主权项

1. A method for replacing compromised digital certificates associated with electronic Universal Integrated Circuit Cards (eUICCs) included in mobile devices, the method comprising:
at an eUICC management server:
receiving an indication that a signing authority associated with a plurality of digital certificates has been compromised; andfor each digital certificate of the plurality of digital certificates:
identifying (i) an eUICC associated with the digital certificate, and (ii) a mobile device in which the eUICC is included, andcausing the eUICC to replace the digital certificate with an updated digital certificate when the updated digital certificate is newer than the digital certificate.
