New states of Germany Germany thus consists of 16 states with equal legal statuses. Yet the process of the "inner reunification" between the former East and West Germany is still ongoing. Persisting differences in culture and mentality among the old East Germany and old West Germany are often referred to as the "wall in the head" ("Mauer im Kopf"). "Ossis" ("Easties") are stereotyped as racist, poor and largely influenced by Russian culture. "Wessis" ("Westies") are usually considered snobbish, dishonest, wealthy, and selfish. 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 a block cipher in 1977. Their attack used a space–time tradeoff to break the double-encryption scheme in only twice the time needed to break the single-encryption scheme. In 2011, Bo Zhu and Guang Gong investigated the "multidimensional meet-in-the-middle attack" and presented new attacks on the block ciphers GOST, KTANTAN and Hummingbird-2. Assume someone wants to attack an encryption scheme with the following characteristics for a given plaintext "P" and ciphertext "C": where "ENC" is the encryption function, "DEC" the decryption function defined as "ENC" (inverse mapping) and "k" and "k" are two keys. The naive approach at brute-forcing this
