Is it possible to use the knapsack problem for digital signatures? What I am imagining is something like the Merkle–Hellman knapsack cryptosystem, but used for digital signing, rather than encryption. It seems that the knapsack problem is well suited to the task of demonstrating authenticity, but I can't quite figure out how it might be done.
