The 3-subset meet-in-the-middle attack is a cryptographic technique used to solve certain problems, particularly in the context of breaking symmetric key algorithms or finding certain types of secret values in a more efficient manner than brute force methods. It is a variation of the general meet-in-the-middle attack, which exploits the structure of the problem to significantly reduce the computational effort required when searching through a key space or solving a problem with an exponential number of possibilities.
