RSA: More about attacks

RSA: More about attacks

RSA: More about attacks. Need to take care with the implementation, e.g.: Do not take p or q very small. Difference of p and q should not be very small. More subtle, e.g.: Thm: If 3d < n^{ ¼ } and q<p<2q, then d can be found in polynomial time. More info: Section 6.2.
