We show that for low public exponent rsa, given a quarter of the bits of the private key an adversary can recover the entire private key. Similar results (though not as strong) are obtained for larger values of e. For instance, when e is a prime in the range N 1=4 ; N 1=2 ], half the bits of the private key suuce to reconstruct the entire private key. Our(More)
