5. The triple DES algorithm applies the DES algorithm three times in succession. This is illustrated in the following equation, where P is transformed into C. C = E (D ( E (P, K[1]), K[2]), K[1]) = E (P, K) This formula shows an "equals" relationship between triple DES and single DES. When does this occur?
