Definition und Eigenschaften. Definiert wird die Kontravalenz durch die Wahrheitswertefunktion ihres Junktors: Eine Kontravalenz ist genau dann wahr, wenn beide durch sie verbundenen Aussagen unterschiedliche Wahrheitswerte haben, wenn also entweder die eine oder die andere wahr ist, aber nicht beide zugleich wahr oder beide zugleich falsch sind. Der lateinische …

XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or from mathematical logic; that is, a true output results if one, and only one, of the inputs to the gate is true.If both inputs are false (0/LOW) or both are true, a false …

In computing, a linear-feedback shift register (LFSR) is a shift register whose input bit is a linear function of its previous state.. The most commonly used linear function of single bits is exclusive-or (XOR). Thus, an LFSR is most often a shift register whose input bit is driven by the XOR of some bits of the overall shift register value.

In cryptography, the simple XOR cipher is a type of additive cipher, an encryption algorithm that operates according to the principles: . A 0 = A, A A = 0, A B = B A, (A B) C = A (B C), (B A) A = B 0 = B,. where denotes the exclusive disjunction (XOR) operation. This operation is sometimes called modulus 2 addition (or subtraction, which is identical). With this logic, a string of text can …

Kademlia is a distributed hash table for decentralized peer-to-peer computer networks designed by Petar Maymounkov and David Mazières in 2002. It specifies the structure of the network and the exchange of information through node lookups. Kademlia nodes communicate among themselves using UDP.A virtual or overlay network is formed by the participant nodes.

This is a list of operators in the C and C++ programming languages.All the operators listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading.. When not overloaded, for the operators &&, ||, and , (the comma operator), there is a sequence point after the evaluation of the first operand.

La fonction OU exclusif, souvent appelée XOR (eXclusive OR) ou disjonction exclusive, ou somme binaire en cryptographie où il est noté +, ou encore ⊻ en algèbre relationnelle, est un opérateur logique de l'algèbre de Boole. À deux opérandes, qui peuvent avoir chacun la valeur VRAI ou FAUX, il associe un résultat qui a lui-même la valeur VRAI seulement si les deux …

Alternatively, an XOR gate is made by considering the disjunctive normal form ¯ + ¯, noting from de Morgan's Law that a NAND gate is an inverted-input OR gate. This construction uses five gates instead of four.

Equivalencias, simplificación, e introducción. La disyunción exclusiva puede ser expresada en términos de conjunción lógica (), disyunción lógica (), y negación de la siguiente manera: = () La disyunción exclusiva puede ser expresada de la siguiente manera: = () Esta representación del XOR puede resultar útil en la construcción de un circuito o una red, ya que sólo tiene un ...
