Smartcard RSA Level 2

by Lehrstuhl für Kryptologie u. IT-Sicherheit, Ruhr-Universität Bochum, published on 10/25/2010

To achieve a very fast decryption in RSA, one might choose the secret key to be rather small. It should, however, not be too small, since then it might be possible to mount brute-force attacks. The same holds for variants like RSA-CRT.
