Title:
WIRELESS NETWORK SERVICE ACCESS CONTROL WITH SUBSCRIBER IDENTITY PROTECTION
Document Type and Number:
WIPO Patent Application WO/2019/210461
Kind Code:
A1
Abstract:
A device level lock policy, which applies to all smart secure platform (SSP) applications of a mobile device, is used to determine whether a particular SSP application can be activated. A tamper resistant hardware secure element (SE) includes a primary platform with a low level operating system (OS) and one or more SSP applications within one or more secondary platform bundles that include secondary platforms with high level OSs specific to the secondary platform bundles. The low level OS enforces the device level lock policy for all secondary platform bundles by verifying whether a lock policy for the SSP application is consistent with the device level lock policy. When verification succeeds, activation is allowed, and when verification fails, activation is disallowed. Subscription identifiers are not provided in unencrypted form to processing circuitry of the mobile device external to the tamper resistant hardware SE to provide subscriber identity privacy protection.
