Summary
| Description |
English: A MAC cryptosystem uses three algorithms: a random number generator (the die) to generate a secret key , to create a MAC for a message , and to verify the MAC.
Deutsch: Ein MAC-Kryptosystem besteht aus drei Algorithmen: einem Zufallszahlengenerator (symbolisiert durch den Würfel) um einen geheimen Schlüssel zu erzeugen, um zu einem Klartext einen MAC zu erzeugen, und , um den MAC zu verifizieren. |
