Partial Exposure Key Attacks on RSA
by Theodosis Mourouzis
We study the attacks on RSA scheme when partial secret information is available. We focus on the following fundamental questions: (A) how many bits of secret key d does an adversary require in order to reconstruct all of d?, (B) How many randomly located bits from the prime divisor of p of the modulus N are required in order to factorize the modulus completely and efficiently?
