We are going to implement AES CRYPT/DECRYPT Protocol over BLE to add some additional protection against HACKing with use of HW &quot; 6.6 CRYPTOCELL&quot; the MODULE of nRF52 MCU. Please, explain some questions: 1. IS it possible to use &quot;6en-USTelligent Community 13Wed, 09 May 2018 15:08:35 GMThttps://devzone.nordicsemi.com/thread/131564?ContentTypeID=1Wed, 09 May 2018 15:08:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9b56c146-54bb-4a1c-90e2-253c46042678Edvin<p>Hello,</p> <p>I am sorry for the late reply. I assume that you are talking of the ARM TrustZone CryptoCell 310 which is on the nRF52<strong>840</strong>, but not on the nrf52<strong>832</strong>.&nbsp;</p> <p>Have you seen the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v15.0.0%2Fnrf_crypto_aes_example.html">AES example in our SDK</a>?</p> <p>&nbsp;</p> <p>You can also read about the cryptocell on the nRF52840 on page 124 in the product <a href="http://infocenter.nordicsemi.com/pdf/nRF52840_PS_v1.0.pdf">spec</a>.</p> <p>&nbsp;</p> <p>Best regards,</p> <p>Edvin</p> <p>&nbsp;</p><div style="clear:both;"></div>
