| Abstract;Each time-memory trade-off cryptanalysis for a block cipher consists of two phases: (1) precomputation of a number of tables and (2) key searching using the tables. This paper proposes to adopt bit-slice implementation of the target block cipher for the precomputation phase. Computer experiments on DES confirm that the proposed method is actually effective to reduce the time for precomputation. (author abst.) |
