Phân tích 64 lược đồ hàm nén trong mô hình hàm băm dựa trên mã khối
Abstract— Constructions for hash functions based on a block cipher have been studied where the size of the hashcode is equal to the block length of the block cipher and where the key size is approximately equal to the block length. In this paper, we have analyzed in more detail 64 general model schemes which has been represented by B. Preneel et al. using five basic attacks. An classification of these schemes also have been done in more detail by considering linear transformations of the inputs. More over, we have investigated the security for one of the secure schemes under the differential cryptanalysis, others are similar.
