We need...
...an article titled "public key." :-) --Larry Sanger 13:54, 3 October 2008 (CDT)
- OK; added more redirects. Give me a little while as I am creating a series of articles with mutual definitions. Howard C. Berkowitz 14:09, 3 October 2008 (CDT)
Broader scope?
I think this needs to compare & contrast the typical hierarchical PKI and the PGP web of trust. The current text seems to describe only the former. Granted, most PKIs work that way and many people use "PKI" to mean exclusively that, but PGP's an important application, it uses a fundamentally different model, and there are arguments that its model is in some ways better.
For example, the opening paragraph currently has:
- The first essential element of PKI is that the creators of public-private keys key pairs have a secure way to store the public key in an accessible repository, with the stored key autheticated as coming from the purported source. The second essential element is that users of the public key have a secure way to retrieve the public key for a given source of information. As with any security tool, there must be a reliable means of auditing changes to the system resources, such as the entry of new keys, with a log verifying that the change was authenticated.
and all of that is indeed essential if the user is expected to trust the repository, to assume any key he gets from there is OK. However, if the user only trusts keys and does his own checking of signatures, then none of it is needed except perhaps for the tricky problem of managing key revocation.
