Hi, Differences between DOMSEC 07 and DOMSEC 08 1) A few typos. 2) Russ Housley's comments made in message "Re: WG Last Call: draft-ietf-smime-domsec-07.txt" 9th January 2001. Including extra text else where in the draft to support some of these comments. 3) Added text in section 5, point 3) a), sub point five, "If local policy requires the message to be encrypted using S/MIME encryption before leaving the domain then encapsulate ...". Also, added the paragraph: - "If local policy does not require the message to be encrypted using S/MIME encryption but there is an envelopedData at a lower level within the message then the 'domain signature' MUST be encapsulated by an envelopedData as described above" This is because a MLA will strip off the outer signatures down to the enveloped data thereby removing the domain signature. Also added the paragraph: - "An example when it may not be local policy to require S/MIME encryption is when there is a link crypto present." 4) Section 5 point 5) added the paragraph: - "If local policy does not require the message to be encrypted using S/MIME encryption but there is an envelopedData at a lower level within the message then the 'domain signature'MUST be encapsulated by an envelopedData as described above" 5) Section 5.1. Added the statement: - "All of the signedData objects are valid and none of them are a domain signature. If a signedData object was a domain signature then it would not be necessary to validate any further signedData objects." 6) Section 5.1, examples 4) and 6). Added text to cover situation where local policy does not require S/MIME encryption. 7) Section 5.1. A new example 7) to show how a message with two envelopedData objects is handled.
