Integral attack pada reduced round algoritme SLIM

---

Abstrak:
Algoritme SLIM merupakan salah satu algoritme kunci simetris block cipher dengan struktur feistel. Penelitian ini meguji ketahanan Algoritme SLIM terhadap integral attack dengan mengaktifkan satu hingga empat nibble pada posisi ??1hingga ??4 dalam semua kemungkinan posisi. Penelitian dimulai dengan mengenkripsi himpunan 16 plaintext atau ? ??????? untuk menemukan integral distinguisher. Hasil pencarian integral distinguisher,
ditemukan integral distinguisher 3 round sebanyak 3 distinguisher, 4 round sebanyak 8 distinguisher, dan 5 round sebanyak 4 distinguisher. Integral
distinguisher ini memiliki 16 unbalanced nibble yang dapat digunakan untuk melakukan recovery kunci.Proses recovery kunci melibatkan pencarian irisan kandidat-kandidat kunci dari tiga ? ??????? setiap integral distinguisher. Penelitian yang dilakukan hanya dapat menemukan kunci round ketiga dan kunci round keempat. Kunci round ketiga didapatkan dari dekripsi ? ??????? yang memiliki integral distinguisher tiga round, dan kunci round keempat dengan integral distinguisher empat round. Penerapan integral attack pada algoritme SLIM dengan mengaktifkan satu hingga empat nibble dengan seluruh variasi posisi tidak efektif pada full round algoritme SLIM karena setelah lima round, seluruh nibble pada algoritme SLIM sudah unbalanced dengan kata lain, full round algoritme SLIM aman terhadap integral attack.

Abstract:
The SLIM Algorithm is one of the symmetric key block ciphers algorithm with a feistel structure. This research examines the resilience of the SLIM Algorithm against integral attacks by activating one to four nibbles at positions ??1 to ??4 in all possible positions.The research starts by encrypting a set of 16 plaintexts or ? ????????? to discover integral distinguishers. As a results of the search for integral distinguishers, three distinguisher of 3 rounds, eight distinguishers of 4 rounds, and four distinguishers of 5 rounds are found. These integral distinguishers have 16 unbalanced nibbles that can be used for key recovery.The key recovery process involves searching for candidate key intersections from three ? ????????? for each integral distinguisher. The conducted research can only identify the third-round key and the fourth-round key. The third-round key is obtained from the decryption of the ? ??????? with a three-round integral distinguisher, and the fourth-round key with a four-round integral distinguisher. Applying an integral attacks on the SLIM algorithm by activating one to four nibbles with all position variations is not effectively on full round SLIM algorithm because after five rounds, all nibbles in the SLIM algorithm become unbalanced, in other word, the full round of the SLIM algorithm resistant to integral attacks.
