    Abstract

    ABSTRACT Sudarmono. 2006. APPLICATION OF DES ALGORITHM AND CRYPTANALYSIS BY USING PROBABILITY THEORY AT ATM CARD, Faculty of Mathematics and Natural Sciences, Sebelas Maret University. Cryptography is an art or science used to take care of security and data secret or information in order not to know by one who have no business. Reverse of cryptography is cryptanalysis, that is art or science to solve encoding secret without passing the way of which ought to. DES algorithm represent one of the symmetry cryptography algorithm used to protect data in the field of banking, that is to make encoding in card of an ATM. The Objective of this thesis writing is to know the determination process of PIN in ATM card which is using DES algorithm and can solve encoding secret of DES algorithm at ATM card using probability theory. ATM which is discussed in this thesis is ATM Eurocheque. Research method which is used in writing of this thesis is literature study and simulation. As for stages, steps taken is beforehand formulate process of encryption and decryption data use DES algorithm later, then application of DES algorithm in security system of ATM that is to determine four PIN digit in ATM. The next step is using theorys in probability conducted cryptanalysis in security system of ATM. From the analysis in this thesis, it can be concluded that DES algorithm which is used in the security system of ATM is still open opportunity to cryptanalys to conduct cryptanalysis on that system. By knowing the magnetic stripe data in an ATM, a cryptanalys can guess four PIN digit which used by the consumer of an ATM by using probability theory.
