How to get certain value from matrix multiplication?

Hello everyone, sorry if this is a basic question. I have two matrix
a = [1 0 0 1]
and
b = [1 0 1 1 0 0 0
1 1 0 0 0 0 1
0 0 1 0 1 1 0
1 0 0 0 1 0 1]
I multiply these two using modulo operation, so it will become
c = [0 0 1 1 1 0 1]
What i want to ask is, is it possible to get the exact value of a if have the c first? Something like a reverse operation to find a from c, but i don't know what to do with b. If it is possible, how is the correct way to do that? Thank you.

If c is the result of modulo(a*b,2) then there might not be a unique solution. I.e., there might be multiple different a's that would work. How do you plan to deal with that? Or is any a that works acceptable? How large can the dimensions of everything be?
