Which is Cortex M4 core does stm32f437xx use?
The STM32F437xx and STM32F439xx devices are based on the high-performance Arm ® Cortex®-M4 32-bit RISC core operating at a frequency of up to 180 MHz. The Cortex-M4 core features a Floating point unit (FPU) single precision which supports all Arm® single-precision data-processing instructions and data types.
How is plaintext divided in AES 128 mode?
We can see it in Fig. 1, the plaintext is divided into blocks as the length of the block of AES, 128. So the ECB mode needs to pad data until it is same as the length of the block. Then every block will be encrypted with the same key and same algorithm. So if we encrypt the same plaintext, we will get the same ciphertext.
