Abstract
An improvement is made to a recently proposed protocol by Wolf (1998). Privacy amplification is achieved for communication over an insecure and non-authentic channel for sufficiently large n, the size of string S shared by the two parties, when the adversary´s Renyi entropy about S exceeds only n/2 rather than 2n/3
