Encryption

Symmetric Key/ Private Key

With the increased use of digital archives because of evolving multimedia sources, comes with it an immense amount of data. When two different parties for an entity like a multimedia source have access to all this data, they need to protect it-and they use a Symmetric Key when they want to be able to have only the two parties relay this information. Essentially the person/group sending the information has to have the same algorithm that the receiver does in order to receive it. However with this ability to have two parties to relay what now is encrypted data makes it the most susceptible encryption type to be targeted for an attack, opposed to a Public Key. An example of a symmetric key would be The German Enigma Machine that sent encrypted information from the Nazi's central location to send secret messages to troops in various locations. Therefore, when the Allies captured one of these machines, they were able to decipher the information encoded within the messages.
