The discussion of modes has some issues: - RFC9052 defines "Direct Encryption" mode, with conflicting meaning. - There is no need to have two modes: Bulk encryption algorithms work on layer 0 (by definition). And by RFC9052 section 5.3, placing bulk encryption algorithm as recipient of an AEAD algorithm will cause it to encrypt the CEK instead of message. -Ilari _______________________________________________ COSE mailing list -- [email protected] To unsubscribe send an email to [email protected]
