Topic: When have people made a POW problem from encryption rather than hashing? (Read 132 times)

I found that Skein, a cryptographic hash function uses a variant of the Matyas–Meyer–Oseas hash with Threefish as its encryption function. Skein is used as one of the POW problems in MyriadCoin.

So the kind of POW problem that I was thinking of is like this:
1. Suppose that E is an encryption function (such as 256 bit AES). Find a suitable hash k along with a 1 block string x so that E_k(x) XOR x
2. Suppose that E is an encryption function (such as 256 bit AES). Find a suitable hash k along with a 1 block string x so that E_k(x) XOR x XOR k
This way people can use encryption rather than the conventional hashes as their POW problem.
