[National Technology N32WB452 Review] 5. Encryption Algorithm Library [Copy link]

 

This evaluation tests the ALGO routines in the built-in SDK, including random number generation, HASH algorithm, and DES/TDES/AES algorithm encryption.

Add the following statement to the main function of the SDK routine:

DES_Version(&type, &customer, date, &version);

Among them, type, customer, version are unsigned char, and date is unsigned char[3]. After running, print to view the corresponding version and update date of the algorithm library, and then use the overloaded printf function to print the algorithm library version information from the serial port. After compiling and downloading to the development board, open the serial port debugging assistant and observe the serial port print information, as shown in the following figure:

From the printed information, we can see that the algorithm library version is 1.1, followed by random number generation, information encryption, and DES/AES algorithm testing.

In summary, N32WB452 has relatively complete support for the cryptographic algorithm library. At the same time, it has a built-in cryptographic algorithm hardware acceleration engine, which performs well in cryptographic processing. It may have great application prospects in smart furniture such as smart locks.

Can all microcontrollers use random number generation?

Can you recommend any information on HASH algorithm and DES/TDES/AES algorithm encryption? Technical articles or books are fine.

According to the official manual, I think this library should be optimized for n32, and other microcontrollers may have a lower speed.

I don’t know much about encryption, I can ask others.
