Fixed point attack dan collision attack pada 4 secure-PGV hash function schemes berbasis algoritme improved-DLBCA

---

Abstrak:
Dalam rangka mendukung perkembangan teknologi infrormasi dan juga aspek keamanannya, khususnya pada perangkat Internet of Things (IoT) dan aspek integritas data, diterapkanlah block cipher-based hash function. Salah satu contoh block cipher-based hash function adalah 4 secure-PGV schemes berbasis algoritme Improved-DLBCA. Kriteria fungsi hash yang harus dipenuhi adalah pre-image resistance, second pre-image resistance, dan collision resistance. Salah satu celah yang dapat dimanfaatkan oleh penyerang untuk membentuk pesan kolisi adalah properti fixed point yang dimiliki oleh suatu fungsi hash. Pada block cipher-based hash function, keamanannya bergantung dengan keamanan block cipher pembangunnya, sedemikian sehingga perlu diuji juga kekuatan underlying block cipher terhadap fixed point attack. Pada penelitian ini dilakukan fixed point attack terhadap underlying block cipher dan juga fixed point attack dan collision attack terhadap skema fungsi hash. Hasil dari penelitian ini adalah bahwa algoritme Improved-DLBCA rentan terhadap fixed point attack, dan fungsi hash 4 secure-PGV schemes berbasis algoritme Improved-DLBCA juga rentan terhadap fixed point attack serta collision attack. Hasil lain dari penelitian ini adalah bahwa properti fixed point yang dimiliki oleh underlying block cipher juga memengaruhi properti fixed point skema fungsi hash yang dibangun.

Abstract:
To support the development of information technology and its security aspects, especially in the realm of Internet of Things (IoT) devices and data integrity, a block cipher-based hash function is implemented. One example of a block cipher-based hash function is the 4 secure-PGV schemes based on the Improved-DLBCA algorithm. The essential criteria that a hash function must fulfill include pre-image resistance, second pre-image resistance, and collision resistance. One vulnerability that attackers can exploit to create collision messages is the fixed point property possessed by a hash function. In a block cipher-based hash function, its security relies on the security of the underlying block cipher, which necessitates testing the resilience of the underlying block cipher against fixed-point attacks. In this study, fixed point attacks were conducted against the underlying block cipher, as well as fixed point and collision attacks against the hash function scheme. The findings of this research indicate that the Improved-DLBCA algorithm is susceptible to fixed point attacks, and the hash function of the 4 secure-PGV schemes based on the Improved-DLBCA algorithm is also vulnerable to fixed point and collision attacks. Another outcome of this study is that the fixed point property of the underlying block cipher also affects the fixed point property of the constructed hash function scheme.
