The terms can be considered disparaging. In 2009, twenty years after the fall of the wall, a poll found that 22% of
Meet-in-the-middle attack of several functions (or block ciphers) such that the forward mapping through the first functions is the same as the backward mapping (inverse image) through the last functions, quite literally "meeting" in the middle of the composed function. For example, although Double DES encrypts the data with two different 56-bit keys, Double DES can be broken with 2 encryption and decryption operations. The multidimensional MITM (MD-MITM) uses a combination of several simultaneous MITM attacks like described above, where the meeting happens in multiple positions in the composed function. Diffie and Hellman first proposed the meet-in-the-middle attack on a hypothetical expansion
