SECURITY ALGORITHM Identification of a security algorithm. Dependency Notes: 1. D5(030,020) If first, then all 2. D5(050,040) If first, then all 3. D5(020,040) If first, then all 4. D5(070,060) If first, then all 5. D5(060,040) If first, then all Notes: 020 0525, a mode of operation shall be chosen in relation to the chosen algorithm (data element 0527). Some combinations of mode of operation and algorithm are not appropriate.
