I am working on peripheral BLE device, the device accessible from smartphone i am also writing the smartphone app, i want just my app to be able to connect and unpack data from the peripheral deice so i have few questions about BLE security</description><dc:language>en-US</dc:language><generator>Telligent Community 13</generator><lastBuildDate>Mon, 07 Nov 2016 12:53:30 GMT</lastBuildDate><atom:link rel="self" type="application/rss+xml" href="https://devzone.nordicsemi.com/f/nordic-q-a/17550/ble-mac-address-whitelist" /><item><title>RE: BLE mac address whitelist</title><link>https://devzone.nordicsemi.com/thread/67476?ContentTypeID=1</link><pubDate>Mon, 07 Nov 2016 12:53:30 GMT</pubDate><guid isPermaLink="false">137ad170-7792-4731-bb38-c0d22fbe4515:cf6a06d7-728a-4e27-aced-ea996b1c4689</guid><dc:creator>Hung Bui</dc:creator><description>&lt;p&gt;Hi Jack,&lt;/p&gt;
&lt;ol&gt;
&lt;li&gt;
&lt;p&gt;I don&amp;#39;t think it&amp;#39;s possible unless you implement an extra whitelisting or controlling on application layer. One simple way is to require the app to send a &amp;quot;password&amp;quot; in a time window says 10 seconds after connection or the peripheral will disconnect. The peripheral should not disclose any data until the password is written.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;Yes, if the central use public/static address. If the central uses Resolvable random address, the peripheral will store the IRK to resolve.&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;They are the same, at least on our chip.&lt;/p&gt;
&lt;/li&gt;
&lt;/ol&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
