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 the data is encrypted, because an exhaustive search on all possible combination of keys (simple brute-force) would take 2 attempts if the data is encrypted with "k"-bit keys "n" times. The MITM is a generic attack which weakens the security benefits of using multiple encryptions by storing intermediate values from the encryptions or decryptions and using those to improve the time required to brute force the decryption keys. This makes a Meet-in-the-Middle attack (MITM) a generic space–time tradeoff cryptographic attack. The MITM attack attempts to find the keys by using both the range (ciphertext) and domain (plaintext) of the composition
