Judul: Eksplorasi Masalah Logaritma Diskret pada Finite Field G P(2m)
Abstrak: Discrete logarithm problem represents a problem which is defined as modular arithmetic. It is often used to generate a key pair on public key cryptography as security object. Given cyclic group G of order n, αgenerator of G, and β∈􀜩, then, in general, discrete logarithm problem is determined as the integer 􀝔, 0≤􀝔≤􀝊−1, such that α􀯫≡β(mod 􀝊). In Menezes et al. (1997) the algorithm to solve the discrete logarithm problem in common cyclic group G are Exhaustive Search algorithm, Baby-Step Giant-Step, Pollard's rho, Pohlig Hellman and Index Calculus. Furthermore, these algorithms are explored to determine the solution of discrete logarithm problem on 􀜩􀜨(2􀯠). The reconstructed algorithms are implemented using Maple 11 software. These implementation can be used to measure security level of cryptography algorithm, which is based on security aspects of discrete logarithm problem
