Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The ARIA block cipher has been established as a Korean encryption standard by Korean government since 2004. In this work,  re-evaluate the security bound of reduced round ARIA-192 and ARIA-256 against meet-in-the-middle MITM key recovery attacks in the single key model.  present a new 4-round distinguisher to demonstrate the best 7 & 8 round MITM attacks on ARIA-192/256. Our 7-round attack on ARIA-192 has data, time and memory complexity of $$2^{113}$$, $$2^{135.1}$$ and $$2^{130}$$ respectively. For our 7-round attack on ARIA-256, the data/time/memory complexities are $$2^{115}$$, $$2^{136.1}$$ and $$2^{130}$$ respectively. These attacks improve upon the previous best MITM attack on the same in all the three dimensions. Our 8-round attack on ARIA-256 requires $$2^{113}$$ cipher calls and has time and memory complexity of $$2^{245.9}$$ and $$2^{138}$$ respectively. This improves upon the previous best MITM attack on ARIA-256 in terms of time as ll as memory complexity. Further, in our attacks,  are able to recover the actual secret key unlike the previous cryptanalytic attacks existing on ARIA-192/256. To the best of our knowledge, this is the first actual key recovery attack on ARIA so far.  apply multiset attack - a variant of meet-in-the-middle attack to achieve these results.
