Abstract

In this paper, we consider security-privacy issues in authentication techniques based on the extraction of common randomness. We demonstrate that the key rate-privacy leak pairs can be enhanced using reliable components extraction from specially designed random projections. The decrease of bit error probability is estimated and its impact on the key rate and privacy leak is evaluated. Several authentication schemes with new helper data protocol are proposed.
