| Description |
In 1994 Lai considered higher order derivatives of discrete functions andintroduced the concept of higher order differentials. We introduce the conceptof partial differentials and present attacks on ciphers presumably secureagainst differential attacks, but vulnerable to attacks using higher order andpartial differentials. Also we examine the DES for partial and higher orderdifferentials and give a differential attack using partial differentials on DESreduced to 6 rounds using only 46 chosen plaintexts with an expected running time of about the time of 3,500 encryptions. Finally it is shown how to find a minimum nonlinear order of a block cipher using higher order differentials.
