The IESG has received a request from an individual submitter to consider the following document: - 'Certificate Transparency' <draft-laurie-pki-sunlight-05.txt> as Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-01-24. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The aim of Certificate Transparency is to have every public end- entity (for example, web servers) and intermediate TLS certificate issued by a known Certificate Authority recorded in one or more certificate logs. In order to detect misissuance of certificates, all logs are publicly auditable. In particular, domain owners or their agents will be able to monitor logs for certificates issued on their own domain. To protect clients from unlogged misissued certificates, each log signs all certificates it records, and clients can choose not to trust certificates that are not accompanied by an appropriate log signature. For privacy and performance reasons log signatures are embedded in the TLS handshake via the TLS authorization extension, in a stapled OCSP extension, or in the certificate itself via an X.509v3 certificate extension. To ensure a globally consistent view of any particular log, each log also provides a global signature over the entire log. Any inconsistency of logs can be detected through cross-checks on the global signature. Consistency between any pair of global signatures, corresponding to snapshots of a particular log at different times, can be efficiently shown. Logs are only expected to certify that they have seen a certificate, and thus we do not specify any revocation mechanism for log signatures in this document. Logs are append-only, and log signatures do not expire. The file can be obtained via http://datatracker.ietf.org/doc/draft-laurie-pki-sunlight/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-laurie-pki-sunlight/ballot/ No IPR declarations have been submitted directly on this I-D.
