It can be tunneled (inefficiently) over UDP, but it isn't implemented
on top of UDP.  SCTP is protocol 132; UDP is protocol 17.

See
  http://www3.ietf.org/proceedings/00jul/I-D/sigtran-sctptunnel-00.txt

Or see RFC 2960, or check your /etc/protocols.

Userspace implementations exist, but they typically require raw IP
access, and you'd still need ipsec as described in the referenced
post.
