11Enigma rotor details — This article contains technical details about the rotors of the Enigma machine.Understanding the way the machine encrypts requires taking into account the current position of each rotor, the ring setting and its internal wiring. Physical design… …
12One-time pad — Excerpt from a one time pad In cryptography, the one time pad (OTP) is a type of encryption, which has been proven to be impossible to crack if used correctly. Each bit or character from the plaintext is encrypted by a modular addition with a bit …
13Merkle-Hellman — (MH) was one of the earliest public key cryptosystems and was invented by Ralph Merkle and Martin Hellman in 1978. [Ralph Merkle and Martin Hellman, Hiding Information and Signatures in Trapdoor Knapsacks, IEEE Trans. Information Theory , 24(5),… …
14Linear feedback shift register — [ xor gate provides feedback to the register that shifts bits from left to right. The maximal sequence consists of every possible state except the 0000 state.] A linear feedback shift register (LFSR) is a shift register whose input bit is a… …
15Vigenère cipher — The Vigenère cipher is a method of encrypting alphabetic text by using a series of different Caesar ciphers based on the letters of a keyword. It is a simple form of polyalphabetic substitution.The Vigenère (pronEng|ˌviːdʒɪˈnɛəɹ, veedj ih nair )… …
16Derived unique key per transaction — In cryptography, Derived Unique Key Per Transaction (DUKPT) is a key management scheme in which for every transaction, a unique key is used which is derived from a fixed key. Therefore, if a derived key is compromised, future and past transaction …
17Nazism and occultism — Speculation about Nazism and occultism has become part of popular culture since 1959. Aside from several popular documentaries, there are numerous books on the topic, most notably The Morning of the Magicians (1960) and The Spear of Destiny… …
18Entropy (information theory) — In information theory, entropy is a measure of the uncertainty associated with a random variable. The term by itself in this context usually refers to the Shannon entropy, which quantifies, in the sense of an expected value, the information… …
