You should take a look a this algorithm : http://eprint.iacr.org/2013/551.pdf

- The block size is variable and unknown from an attacker.
- The size of the key has no limit and is unknown from an attacker.
- The key size does not affect the algorithm speed (using a 256 bit key is the same as using a 1024 bit key).
- The algorithm is much faster than the average cryptographic function. Experimental test showed 600 Mo/s - 4 cycles/byte on an Intel Core 2 Duo P8600 2.40GHz and 1,2 Go/s - 2 cycles/byte on an Intel i5-3210M 2.50GHz. Both CPU had only 2 cores.
