Domain Keys Identified Mail BOF (dkim) xxxxxxxx, November x at xxxx-xxxx ================================= CHAIRS: DESCRIPTION: Forgery of headers that indicate message origin is a problem for users of Internet mail. The DKIM working group will produce specifications that permit authentication of message headers during transit, using public-key signatures and based on domain name identifiers. Keys will be stored in the responsible identity's DNS hierarchy. The specifications will describe threats of concern and any limitations in the signature security that is provided. The specification will be based on the draft documents and will make only the minimal changes deemed essential to the viability of the service. The specifications will contain summaries of threats and requirements that are handled by the specified mechanism. The DKIM working group will also address mechanisms for advertising "signing policy" so that a recipient can determine whether a valid message signature should be present. The working group will NOT consider related topics, such as reputation and accreditation systems, and message encryption. It will also NOT consider signatures which are intended to make long-term assertions (beyond the expected transit time of a message) nor signatures which attempt to make strong assertions of the identity of the message author. The working may also study whether to adopt a work item for specifying a common mechanism to communicate the results of message verification to the message recipient.
