RTCWEB WG members may be interested in the following draft:

http://tools.ietf.org/html/draft-miers-tls-sas-00

This draft specifies a Short Authentication String feature for
TLS and DTLS which would allow a pair of communicating
to compare SAS values computed from the TLS/DTLS
handshake in order to detect active attack.
