Algebraic attack pada algoritme simplifikasi Design 32-bit Lightweight Block Cipher (DLBCA) menggunakan metode ElimLin

Serangan aljabar merupakan salah satu serangan yang dapat diimplementasikan pada algoritme stream
cipher dan block cipher. Serangan aljabar pada prinsipnya dilakukan dalam dua langkah. Pertama, teks
terang dan teks sandi yang saling berkorespondensi dengan kunci rahasia yang diberikan dari suatu
algoritme akan ditentukan persamaan polinomialnya. Kedua, solusi unik dari sistem persamaan
polinomial unik tersebut dicari untuk menjadi kunci rahasia yang benar. Solusi dari sistem persamaan
polinomial tersebut dapat diselesaikan dengan menggunakan suatu metode yaitu metode ElimLin.
Penelitian ini dilakukan perancangan simplifikasi algoritme DLBCA. Pada hasil rancangan algoritme
simplifikasi DLBCA dilakukan algebraic attack dengan menggunakan dua skenario yaitu teks terang
acak dan teks terang berpola. Perancangan simplifikasi DLBCA dan algebraic attack berhasil
dilakukan. Persamaan polinomial dengan panjang maksimal 241.915 monomial dari skenario 1 dan
248.613 monomial dari skenario 2 diperoleh dari algebraic attack. --

An algebraic attack is one of the attacks that can be implemented on stream cipher and block cipher
algorithms. The algebraic attack is carried out in principle in two steps. First, plaintext and ciphertext
that correspond to a given secret key of an algorithm will be determined by their polynomial equations.
Second, the unique solution of the unique system of polynomial equations is sought to be the correct
secret key. The solution of a system of polynomial equations can be solved by using a method, namely
the ElimLin method.
This research is designed to simplify the DLBCA algorithm. In the design results of the DLBCA
simplification algorithm, an algebraic attack was carried out using two scenarios, namely random
plaintext and patterned plaintext. The design of DLBCA simplification and the
algebraic attack was successfully carried out. From algebraic attacks, polynomial equations with a
maximum length of 241.915 monomial from scenario 1 and 248.613 monomial from scenario 2 are
obtained.
