Berlin Wall near Potsdamer Platz where the stretch of both walls is marked, giving visitors an impression of the dimension of the barrier system. After the fall of Berlin Wall, there were initiatives that they want to preserve the death strip walkways and redevelop it into a hiking and cycling area, known as Berliner Mauerweg. It is part of the initiative by Berlin Senate since 2005. For many years after reunification, people in Germany talked about cultural differences between East and West Germans (colloquially "Ossis" and "Wessis"), sometimes described as "Mauer im Kopf" (The wall in the head).

Meet-in-the-middle attack "B" where "T" is much smaller than the others. For data complexity see subsection on complexity for MD-MITM. Meet-in-the-middle attack The meet-in-the-middle attack (MITM) is a generic space–time tradeoff cryptographic attack against encryption schemes which rely on performing multiple encryption operations in sequence. The MITM attack is the primary reason why Double DES is not used and why a Triple DES key (168-bit) can be bruteforced by an attacker with 2 space and 2 operations. When trying to improve the security of a block cipher, a tempting idea is to encrypt the data several times using multiple keys. One might
