In the perspective of RSA, given small encryption exponent e (e.g., e = 216 + 1), the top half of the decryption exponent d can be narrowed down within a small search space. This f...
We describe and analyze a new digital signature scheme. The new scheme is quite efficient, does not require the the signer to maintain any state, and can be proven secure against ...
In typical RSA, it is impossible to create a key pair (e, d) such that both are simultaneously much shorter than φ(N). This is because if d is selected first, then e will be of t...
