MSP430F6736A: Data amount of AES GCM Source Code

Do you use IAR or CCS?

Its working only on simulator. Its not running in original MSP430F6736A hardware. Please confirm any possibility of running it on hardware. Thanks

IAR

I have CCS and I do not know how to convert IAR to CCS.
Probably I will need to do it manually.
No time today to do it.

If you have CCS code please share it.

Using CCS8.2, TI v16.9.9.LTS I have some tests working on MSP430FR5994 with AES256.

Original project name renaming and DVT update have delayed me.

Now I am facing real issue with aes128_gcm_tests.c

Probably it is related interrupts.

I need more time.

It is 2:42 A.M. my local time.

Time for sleep.

My partial work is here:

aes128.zip

My problem is the sample code is not working in actual hardware, but working correctly in simulator. In the sample code they given MSP430F67791 and I am using MSP430F67791A. It having 32K RAM. The problem I understood related to stack, it cannot exit from the function. Its looping inside the multiple function calls in side main function. Can anyone please verify it http://software-dl.ti.com/tsu_encryption/tsu_encryption_public_sw/exports/AES_GCM_SOURCE_CODE.ZIP .

Hi,

this post is marked as resolved,no one would help if post is resolved, probably.
Create a new post.

Your original question: Is it possible to implement AES GCM in msp430F6736A?
I have asked you: Please show the error and attache a full console output.
You did not responded.
<<< I have removed some file reading part in the above example and now the linker error is gone. And getting the aes-gcm cipher output correct. But authentication tag is not matching.
You have removed something. Exactly what? I do not seen any file reading part within aes128 examples. Why do you assure that aes-gcm output is correct? How did you checked that?

Now you are saying: My problem is the sample code is not working in actual hardware, but working correctly in simulator. In the sample code they given MSP430F67791 and I am using MSP430F67791A.
What is an actual h/w, what is your simulator?
Do you need to have it working on msp430F6736A or MSP430F67791A?
<<< It having 32K RAM. The problem I understood related to stack, it cannot exit from the function. Its looping inside the multiple function calls in side main function.
Have you compared MSP430F67791 and MSP430F67791A errata sheets?
If not, you should do it.
If the original code does not support MSP430F67791A, how did you implemented interrupts for this MCU?

Please, precisely describe what you need and what is your current project status.
Please, provide versions of tools you use.

If you continue on IAR, I would be unable to help you.
I have CCS8.x and CC7.x versions.

I just need a standalone AES GCM C source code which will work on MSP430F6736A as well as MSP430F67791A. No matter its CCS or IAR, i will convert it. if it is platform independent, it will be a huge help. Thanks in advance.

I send you some code, last night.
aes128_tests.c and aes128_cdc_tests.c are working.
Have you checked that code?

Today I have no time to debug aes128_gcm_tests.c
I do not know MSP430 assembler, at all.
Could take time to cope with a galois assembler code.

Hi,

what is your status? What has solved your issue?

Did you check the output? Can you Please send me the input and output values...

I want to check this input and see the output,

blockCipherKey = {0x00,0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08,0x09,0x0A,0x0B,0x0C,0x0D,0x0E,0x0F};

aad = {0xD0,0xD1,0xD2,0xD3,0xD4,0xD5,0xD6,0xD7,0xD8,0xD9,0xDA,0xDB,0xDC,0xDD,0xDE,0xDF};

IV = {0x4D,0x4D,0x4D,0x00,0x00,0xBC,0x61,0x4E,0x01,0x23,0x45,0x67};

plainText = {0xC0,0x01,0x00,0x00,0x08,0x00,0x00,0x01,0x00,0x00,0xFF,0x02,0x00};

aes128_gcm_tests.c does not work.
NMI issue and as I mentioned before, had no time to fix it.
Late evening I will try to fix it.

Ok Thanks

There is an old AES library which does not uses AES accelerator.
You can find a reference to this lib. I my past posts, like 1-2 months old.

Could you check this?

That is not AES GCM i think
