+
+<p>Android 5.1 introduced a new mechanism to grant special privileges for APIs relevant
+to the Universal Integrated Circuit Card (UICC) owner’s apps. The Android platform will load
+certificates stored on a UICC and grant
+permission to apps signed by these certificates to make calls to a handful of
+special APIs. Since carriers have full control of the UICC, this mechanism
+provides a secure and flexible way to manage apps from the Mobile Network
+Operator (MNO) hosted on generic application distribution channels such as
+Google Play but still have special privileges on devices without the need for
+the apps to be signed by the per-device platform certificate or be
+pre-installed as a system app.</p>
+
+<h2 id=rules_on_uicc>Rules on UICC</h2>
+
+<p>Storage on the UICC is compatible with the <a
+href="http://www.globalplatform.org/specificationsdevice.asp">GlobalPlatform
+Secure Element Access Control specification</a>. The application identifier
+(AID) on card is A00000015141434C00, and the standard GET DATA command is used
+to fetch rules stored on the card. You may update these rules via card
+over-the-air (OTA) update.  Data hierarchy is as follows (noting the
+two-character letter and number combination in parentheses is the object tag).
+(An extension to spec is under review.)</p>
+
+<p>Each rule is a REF-AR-DO (E2) and consists of a concatenation of a REF-DO and
+an AR-DO:</p>
+
+<ul>
+  <li>REF-DO (E1) contains a DeviceAppID-REF-DO or a concatenation of a
+DeviceAppID-REF-DO and a PKG-REF-DO.
+  <ul>
+    <li>DeviceAppID-REF-DO (C1) stores the SHA1 (20 bytes) or SHA256 (32 bytes)
+signature of the certificate.
+    <li>PKG-REF-DO (CA) is the full package name string defined in manifest, ASCII
+encoded, max length 127 bytes.
+  </ul>
+  <li>AR-DO (E3) is extended to include PERM-AR-DO (DB), which is an 8-byte bit mask
+representing 64 separate permissions.
+</ul>
+
+<p>If PKG-REF-DO is not present, any app signed by the certificate will be granted
+access; otherwise both certificate and package name need to match.</p>

+reference on developer.android.com</a> for additional information.</p>
+
+<h2 id=android_platform>Android platform</h2>
+
+<p>On a detected UICC, the platform will construct internal UICC objects that
+include carrier privilege rules as part of the UICC. <a
+href="https://android.googlesource.com/platform/frameworks/opt/telephony/+/master/src/java/com/android/internal/telephony/uicc/UiccCarrierPrivilegeRules.java">UiccCarrierPrivilegeRules.java</a>
+will load rules, parse them from the UICC card, and cache them in memory. When
+a privilege check is needed, UiccCarrierPrivilegeRules will compare the caller
+certificate with its own rules one by one. If the UICC is removed, rules will
+be destroyed along with the UICC object.</p>
+
+<h2 id=faq>FAQ</h2>
+
+<p><strong>How can certificates be updated on the UICC?
+</strong></p>
+
+<p><em>A: Use existing card OTA update mechanism.
+</em></p>
+
+<p><strong>Can it co-exist with other rules?
+</strong></p>
+
+<p><em>A: It’s fine to have other security rules on the UICC under same AID; the
+platform will filter them out automatically.
+</em></p>
+
+<p><strong>What happens when the UICC is removed for an app that relies on the
+certificates on it?
+</strong></p>
+
+<p><em>A: The app will lose its privileges because the rules associated with the UICC
+are destroyed on UICC removal.
+</em></p>
+
+<p><strong>Is there a limit on the number of certificates on the UICC?
+</strong></p>
+
+<p><em>A: The platform doesn’t limit the number of certificates; but because the check
+is linear, too many rules may incur a latency for check.
+</em></p>
+
+<p><strong>Is there a limit to number of APIs we can support via this method?
+</strong></p>
+
+<p><em>A: No, but we limit the scope of APIs to carrier related.
+</em></p>
+
+<p><strong>Are there some APIs prohibited from using this method? If so, how do you
+enforce them? (ie. Will you have tests to validate which APIs are supported via
+this method?)
+</strong></p>
+
+<p><em>A: Please refer to the "API Behavioral Compatibility" section of the <a
+href="{@docRoot}compatibility/android-cdd.pdf">Android Compatibility Definition
+Document CDD)</a>. We have some CTS tests to make sure the permission model of
+the APIs is not changed.
+</em></p>
+
+<p><strong>How does this work with the multi-SIM feature?
+</strong></p>
+
+<p><em>A: The default SIM that gets set by the user will be used.</em></p>
+
+<p><strong>Does this in any way interact or overlap with other SE access technologies e.g.
+SEEK?
+<em>A: As an example, SEEK uses the same AID as on the UICC. So the rules co-exist
+and are filtered by either SEEK or UiccCarrierPrivileges.</em>
+</strong></p>
+
+<p><strong>When is it a good time to check carrier privileges?
+<em>A: After the SIM state loaded broadcast.</em>
+</strong></p>
+
+<p><strong>Can OEMs disable part of carrier APIs?
+</strong></p>
+
+<p><em>A: No. We believe current APIs are the minimal set, and we plan to use the bit
+mask for finer granularity control in the future.
+</em></p>
+
+<p><strong>Does setOperatorBrandOverride override ALL other forms of operator name
+strings? For example, SE13, UICC SPN, network based NITZ, etc.?
+</strong></p>
+
+<p><em>A: See the SPN entry within TelephonyManager:
+<a
+href="http://developer.android.com/reference/android/telephony/TelephonyManager.html">http://developer.android.com/reference/android/telephony/TelephonyManager.html</a>
+</em></p>
+
+<p><strong>What does the injectSmsPdu method call do?
+</strong></p>
+
+<p><em>A: This facilitates SMS backup/restore in the cloud. The injectSmsPdu call
+enables the restore function.
+</em></p>
+
+<p><strong>For SMS filtering, is the onFilterSms call based on SMS UDH port filtering? Or
+would carrier apps have access to ALL incoming SMS?
+</strong></p>
+
+<p><em>A: Carriers have access to all SMS data.</em></p>
+
+<p><strong>Since the extension of DeviceAppID-REF-DO to support 32 bytes appears
+incompatible with the current GP spec (which allows 0 or 20 bytes only) why are
+you introducing this change? Do you not consider SHA-1 to be good enough to
+avoid collisions?  Have you proposed this change to GP already, as this could
+be backwards incompatible with existing ARA-M / ARF?
+</strong></p>
+
+<p><em>A: For providing future proof security this extension introduces SHA-256 for
+DeviceAppID-REF-DO in addition to SHA-1 which is currently the only option in
+the GP SEAC standard. It is highly recommended to use SHA-256.</em></p>
+
+<p><strong>If DeviceAppID is 0 (empty), would you really apply the rule to all device
+applications not covered by a specific rule?
+</strong></p>
+
+<p><em>A: Carrier apis require deviceappid-ref-do be non-empty. Being empty is
+intended for test purpose and is not recommended for operational deployments.</em></p>
+
+<p><strong>According to your spec, PKG-REF-DO used just by itself, without
+DeviceAppID-REF-DO, should not be accepted. But it is still described in Table
+6-4 as extending the definition of REF-DO. Is this on purpose? What will be the
+behavior of the code when only a PKG-REF-DO is used in a REF-DO?
+</strong></p>
+
+<p><em>A: The option of having PKG-REF-DO as a single value item in REF-DO was removed
+in the latest version. PKG-REF-DO should only occur in combination with
+DeviceAppID-REF-DO.
+</em></p>
+
+<p><strong>We assume we can grant access to all carrier-based permissions or have a
+finer-grained control. What will define the mapping between the bit mask and
+the actual permissions then? One permission per class? One permission per
+method specifically? Will 64 separate permissions be enough in the long run?
+</strong></p>
+
+<p><em>A: This is reserved for the future, and we welcome suggestions.</em></p>
+
+<p><strong>Can you further define the DeviceAppID for Android specifically? Since this is
+the SHA-1 (20 bytes) hash value of the Publisher certificate used to signed the
+given app, shouldn't the name reflect that purpose? (The name could be
+confusing to many readers as the rule will be applicable then to all apps
+signed with that same Publisher certificate.)
+</strong></p>
+
+<p><em>A: See the  <a
+href="#rules_on_uicc">Rules on UICC</a> section for details. The deviceAppID storing
+certificates is already supported by the existing spec. We tried to minimize
+spec changes to lower barrier for adoption. </em></p>
