Subject: [OASIS Issue Tracker] Created: (EBXMLMSG-45) PMode parameter for Key Transport algorithm
PMode parameter for Key Transport algorithm ------------------------------------------- Key: EBXMLMSG-45 URL: http://tools.oasis-open.org/issues/browse/EBXMLMSG-45 Project: OASIS ebXML Messaging Services TC Issue Type: Improvement Components: Core Spec Reporter: Pim van der Eijk For encryption, the core specification currently has a PMode PMode[1].Security.X509.Encryption.Algorithm which identifies "the encryption algorithm to be used" based on W3C XML Encryption algorithm identifiers. XML Encryption actually distinguishes two algorithms: xenc:EncryptedData / xenc:EncryptionMethod / @Algorithm The value is an identifier of a block encryption algorithm like http://www.w3.org/2001/04/xmlenc#aes128-cbc or http://www.w3.org/2001/04/xmlenc#tripledes-cbc. xenc:EncryptedKey / xenc:EncryptionMethod / @Algorithm The value is an identifier of an algorithm used for Key Transport. XML encryption currently recommends http://www.w3.org/2001/04/xmlenc#rsa-oaep-mgf1p, commonly used values include http://www.w3.org/2001/04/xmlenc#rsa-1_5. I assume the PMode parameter identifies the first use. There does not seem to be a parameter for the second one? When using WS-SecurityPolicy, it would be needed to select the correct policy, e.g. Basic128Sha256 versus Basic128Sha256Rsa15. (This is not to promote WS-SecurityPolicy, the ebMS3 approach of directly using the W3C Signature and Encryption parameters is actually more future-proof than WS-SecurityPolicy's identifiers, just to note that some implementers of ebMS3 will use security toolkits that are configured using WS-SecurityPolicy). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tools.oasis-open.org/issues/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
