[edit] "Challenge-response" or "challenge-reply"

Hello, can someone clarify whether challenge-response authentication or challenge-reply authentication is the right term? thanks --195.145.211.194 12:02, 28 November 2006 (UTC)

This is the first time I've heard the phrase "challenge-reply authentication". A Google search for the former yields about 118,000 results [1] while challenge-reply yields only 38 [2]. It's a safe bet to say "challenge-response authentication". -- intgr 15:32, 28 November 2006 (UTC)
