Abstract :
In 1998, Shao proposed two new digital signature schemes which were claimed to be unbreakable if the factorisation and the discrete logarithms are simultaneously unsolvable. However, this paper shows that, if the factorisation problem can be solved, Shao´s signature schemes can be broken
