| Abstract(in English) | SHA-O employs a primitive polynomial of degree 16 over GF (2) in its message scheduling. There are 2048 primitive polynomials of degree 16 over GF (2). For each primitive polynomial, a SHA-O variant is constructed. In this paper, the security of 2048 variants is analyzed against the Chabaud-Joux attack proposed in CRYPTO'98. The analysis shows some variants are totally resistant to the attack and the original SHA-0 is not so resistant. Furthermore, a collision in the most vulnerable variant is presented. It is obtained by the original Chabaud-Joux attack without any improvements. |
