look at using a quorum based key distribution and agreement protocol (where quorum == a specific subset of group key management) with regular attestation / rekeying via trusted and strongly authenticated mechanisms. session timeout (for failure / lack of consensus / malicious attack) should be detected within an appropriate time frame for the user to respond securely. (i tend to think 60 seconds is an acceptable window) doing this in a user friendly manner is very difficult and probably the reason prior work in this domain is scarce.
