摘要：In this paper we investigate the security of the server aided
RSA protocols RSA-S1 and RSA-S1M proposed by Matsumoto, Kato and Imai
resp. Matsumoto, Imai, Laih and Yen. We prove lower bounds for the
complexity of attacks on these protocols and show that the bounds are
sharp by describing attacks that almost match our lower bounds. To the
best of our knowledge these are the first lower bounds for efficient
server aided RSA protocols.
