https://devzone.nordicsemi.com/f/nordic-q-a/857/aes-hardware-moduleWe&#39;ve been trying to user the AES hardware module in ECB mode. To do that we used the sd_ecb_block_encrypt function. Is this hardware accelerated? Based on power consumption it seems that it is a software implementation. If it is not hardware accelerateden-USTelligent Community 13Fri, 08 Nov 2013 01:44:39 GMThttps://devzone.nordicsemi.com/thread/4196?ContentTypeID=1Fri, 08 Nov 2013 01:44:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f82ba9b7-da00-47a3-b1a9-28078af4d9b1John Kelley<p>Yes, that should be HW accelerated but may get delayed if you are using encryption in your BLE connection and are actively transferring data. Said another way, you&#39;re sharing that HW block with the SoftDevice.</p> <p>What do you mean by &quot;based on power consumption&quot;? Is it greater than what you would expect for a HW implementation?</p><div style="clear:both;"></div>
