Sheng Liu · Dianzi xuebao · 1999
This paper proposes a protocol that enables communication over public channel to be authenticated by the partially secret common information between the two parties,and makes privacy amplification secure against active adversaries with some probability.At last,the relationship between the block size and the success probability of active attack is analyzed and a lower bound on size of bits of the common string needed to implement privacy amplification is given.
