What is the difference between regular crypto and cryptocell310?

Hello

I'm going to use encryption to send data via Bluetooth.  I am using the crypto AES example using nrf52DK and I found out that nrf52840 supports H/W encryption called cc310.

What is the difference between encryption used by this cc310 and other mcu?
I don't have nrf52840DK, is it better to buy it?

Thank you.

Hello,

We don't use the cc310 to encryption connections, but it can be used to get HW acceleration of other crypto routines at the application layer if you have any. Encryption of the BLE link is done with the AES CCM peripheral which is present on all nRF5x series devices.
