Cryptanalysis with Ternary Difference: Applied to Block Cipher PRESENT
Keywords:
Lightweight block cipher PRESENT, signed difference, ternary difference cryptanalysis.Abstract
Signed difference approach was first introduced
by Wang for finding collision in MD5. In this paper we
introduce ternary difference approach and present it in 3 symbols. To show its application we combine ternary difference approach with conventional differential cryptanalysis and apply that to cryptanalysis the reduced round PRESENT. We also use ant colony technique to obtain the best differential characteristic. To illustrate the privilege in the result of experiment, we calculate advantage of the attack.
