I am writing a program to control an old camera over serial. I have no access to the protocol or source code of the demonstration program that i have, but i can generate some correct checksums by monitoring the communications in wireshark.

The length of the packets changes depending on what function i perform, and seems to sometimes change depending on the values of the contained data. (FF sometimes repeats in longer frames, although i cant be sure that these arent just errors)

The last 2 bytes of data are the checksum i assume. Other parts are the message function and data. In the packet below, the 01 46 corresponds with the value 326 which the software reports.

10 02 41 02 20 01 46 10 03 cb a4

I personally cant see an obvious pattern to the checksum. The first byte seems to increment by 0x10 nicely with the data for a while, before jumping around then decrementing by 0x10, acting erratically.

Does this seem familiar to anyone? How can I go about determining the algorithm to generate the checksum on an arbitrary message?

Ill attach lots of data for you to look at:

  • Did you try reveng on your data? Although it doesn't seem like a CRC to me, with the 2nd-to-last byte changing its value so neatly, maybe it'll find something. – Guntram Blohm Mar 26 '15 at 9:52

    Also, if you have a link to a downloadable version of the demo program, please post it; if there's no obfuscation, it might be quite easy to pull the algorithm from the program once it's loaded in Ida, and there have been cases here where users took this kind of question for a challenge. – Guntram Blohm Mar 26 '15 at 10:03

I'm not sure it's a checksum either. FF may be used as a padding flag. Also I think your "record size" needs to be reevaluated. I see this as a series of bytes that start with 10 02 xx yy yy zz zz x and y might be options z looks like data or a sequence (ish) Then the next record looks like this 10 03 xx xx Here's an observation on the 10 03 records: 10 03 d2 26 10 03 c2 07 10 03 f2 64 10 03 e2 45 looking at the last 2 bytes,

0xD226 - 0xC207 = 0x101F

0xF264 - 0xE245 = 0x101F

I don't know what that means, but I think that relationship is not coincidence.

I took the data and did some binary find and replace to shift it from one line with two records to two lines, one of each record type. Specifically, I added three leading bytes to 0x1002, removed those bytes at the very start to align the first record with the start of the file. Then they aligned nicely. However, when I found the FF, I saw that the records got misaligned, hence more evidence that its some sort of padding flag or something to keep the protocol on track, I guess. I added null bytes to shift the records back into conformance. I'll paste the results below, but only partial, because of the hastiness of my find and replace I think a portion of the data towards the end got borked up and I had "run out of time" to mess with it. I'll leave a little bit of where things got shifted, but keep in mind I tinkered with it a bit so I don't think I preserved it as well as the first section.

Edit: That last byte of the 0x1002 record might be some sort of counter, note that when it becomes a full byte that's when some sort of sequence starts to reset. Search for this string 10 02 41 02 20 00 FF

PS: Politely, it would have been nice to know what you were doing with the hardware to generate this data, some context for the evaluation may have been helpful.
