https://devzone.nordicsemi.com/f/nordic-q-a/67523/nordic-cryptocell-310-using-nrf52840-dkHello, I am a bit confused with the ARM Cryptocell 310 engine. As I can see this software is proprietary but in nrf5 sdk there is the cryptocell engine as external library (i.e .a). I am using zephyr withe nrf 52840-dk and I am interested to integrateen-USTelligent Community 13Thu, 22 Oct 2020 12:40:34 GMThttps://devzone.nordicsemi.com/thread/276440?ContentTypeID=1Thu, 22 Oct 2020 12:40:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0fe62d9f-064f-438f-88ce-e4fc62c53802Einar Thorsrud<p>Yes, that is correct.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/276428?ContentTypeID=1Thu, 22 Oct 2020 11:59:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:452bf7ca-d32c-4527-ba32-1a02b0fa1faeNikos Karamolegkos<p>Thanks, Therefore, I can somehow integrate the code of the crypto examples of the nrf5 sdk to the zephyr project using the nordic cryptocell 310 library. I just have to link the library to my project</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/276422?ContentTypeID=1Thu, 22 Oct 2020 11:37:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:72c44488-4886-4032-9e62-7723691713ecEinar Thorsrud<p>Hi,</p> <p>The CryptoCell IP is part of the nRF52840 IC, and Nordic pays ARM to include that IP. You do not need to pay ARM (or anyone else) to use that or the accompanying software as it is part of the cost when you pay for the IC itself. You can find documentation for the relevant libraries for Zephyr/NCS <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrfxlib/crypto/README.html">here</a>.</p><div style="clear:both;"></div>
