Hi,

Does the Bus Encryption Engine encrypt as well as decrypt?

For example, if I was running an Encrypted XIP application (from serial nor flash), and I wanted it to write something to a different area of flash, what happens? Is it encrypted when writing, and decrypted when reading? Or are all read/writes to flash in plaintext, and only reads of the bootable image decrypted on the fly?

Many thanks.

Hello, 

Does the Bus Encryption Engine encrypt as well as decrypt?

No, the BEE is implemented as an on-the-fly decryption engine only. 


Have a great day,
Victor

What should I do if I have access to flash and write data to flash at the same time?
