UJI KEACAKAN SIMPLIFIED IDEA DAN SIMPLIFIED IDEA PADA SKEMA DAVIES-MEYER DENGAN STRICT AVALANCHE CRITERION (SAC)
Abstract
Pada paper ini dilakukan pengujian keacakan algoritma simplified IDEA dan simplified IDEA pada skema Davies-Meyer. Pengujian dilakukan dengan Strict Avalanche Criterion (SAC) bertujuan untuk menentukan sifat difusi yang dimiliki simplified IDEA pada mode block cipher dan dalam bentuk fungsi hash dengan skema Davies-Mayer Hasil pengujian SAC pada algoritma simplified IDEA dan simplified IDEA pada Skema Davies-Meyer dinyatakan tidak lulus uji SAC dikarenakan nilai observasi yang dihasilkan menjauhi nilai yang diharapkan sehingga nilai hitungnya lebih besar daripada tabel ( =0,01 dan derajat kebebasan =4).
Kata kunci: fixed point attack, simplified IDEA, Davies- Meyer.
