This article does not tell what I would like to know: how exactly it is possible to be sure I know the password without knowing the password. Yecril 19:59, 28 July 2007 (UTC)
To authenticate yourself to at least one of the banks in the UK, you are asked to provide a certain letter from your password (ie, the first, or the seventh or both). In that case, the password is never revealed, but the callcenter worker can verify that the letters are correct. Dutchdavey 12:18, 3 September 2007 (UTC)
I deleted the old page and simply put in a link to password-based authentication. I am a cryptographer and have never seen the terminology "zero-knowledge password proof" in the technical literature, nor is it clear to me how it would be any different from what is already achieved by password-based key-exchange protocols. —Preceding unsigned comment added by 128.8.131.12 ( talk) 23:36, 14 February 2008 (UTC)
I still maintain that the terminology "ZKPP" is never used in the technical literature. (Or, if it is used, it is not common.) Again, as far as I am aware a ZKPP as referred to by this article is equivalent to password-authenticated key exchange. —Preceding unsigned comment added by 128.8.131.12 ( talk) 20:44, 26 February 2008 (UTC)
Most of the "old page" content that was deleted by 128.8.131.12 has been reverted. Some content was left deleted, as being unnecessarily duplicative of the content of password-authenticated key exchange (PAKE). However, the term ZKPP clearly deserves a page of its own since it is not a synonym of PAKE; Rather, a ZKPP is merely one of the things that may be provided by a PAKE protocol, other things being mutual authentication and key exchange. Similarly, zero-knowledge proof is not a synonym for commitment_scheme. A literature reference has been added from a technical standard. The parenthetical remark about ZKPPs not being "zero knowledge" was replaced with a more accurate statement about a ZKPP and a ZKP are the same, and how a ZKPP differs from other kinds of zero-knowledge proofs. — Preceding unsigned comment added by 72.72.33.235 ( talk) 23:20, 12 October 2008 (GMT)
of the content of password-authenticated key exchange (PAKE)", when said article doesn't exist, and appears to have never existed (no entry in its deletion logs)?! A search for the term, however, reveals the more broad article on password-authenticated key agreement, but it doesn't even have a dedicated section for "PAKE". -- Jokes Free4Me ( talk) 18:08, 28 June 2013 (UTC)
