Most data streams are not authenticated in -either direction, and most of those that are authenticated in at least -one direction use authentication regimes which suffer from a range of -known structural problems. - -Public-key-based authentication offers security advantages over -shared-secret approaches, but it introduces additional questions of -key distribution, binding, and revocation. Two common solutions to -these problems on today's network are X.509 certificates (used by TLS -connections like HTTPS) and so-called "key continuity management" -(KCM) (used by popular SSH implementations and the "security -exceptions" interface for some web browsers). Both of these schemes -present security concerns of their own: KCM has trouble with initial -contact, key revocation, and re-keying; and X.509's single-issuer -certificate format has a systemic bias that selects for unaccountable -third-party authorities.

As a simple, -alternative PKI, the Monkeysphere resolves these failings, and also -provides features currently only available as protocol extensions -(such as SNI). - -
