Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely:  provide an attack to (EC)DSA digital signature built upon Coppersmith's method.  prove that, if a , k are the private and ephemeral key, respectively, of the (EC)DSA scheme and ( k - 1 mod q ) 2 a < 0.262 ? q 1.157 , then  can efficiently find a.  apply a variant of Coppersmith's method to the Digital Signature Algorithm. use a Boneh-Durfee type lattice attack.Our attack is feasible if the product of the keys k - 1 ? a is small.
