umm.... that should be "TLS over SCTP", shouldn't it?RFC Editor Note In the following sentence: This extra layer sometimes requires ordered delivery of messages from the transport layer (e.g., TLS [6]). Add a normative reference to RFC 3436 (SCTP over TLS). Replace Section 6 Security Considerations The security issues raised in [2] are not worsened by SCTP, provided the advice in Section 4 is followed and SCTP over TLS [cite RFC 2436] is used where TLS would be required in [2].
