In general I think this seems like a good idea (even though I've not yet 
studied the details).

What did struck me at once when reading the introduction was the phrase:

    Users can safely input sensitive data to the web forms after confirming
    that the mutual authentication has succeeded.

... but you only authenticated fine, there's no protection against 
eves-droppers in these scheme! A user would only be "safe" to "input sensitive 
data" if the connection is also protected in some other means which is beyond 
the scope of this protocol but still I think the way that is written is 
slightly misleading.
