+1 to that.  Lots of people say it that way:  Forward Secrecy.

Occasionally, Forward Secrecy must be distinguished from something
similar, such as LAaFS i.e. Lame Attempt at Forward Secrecy ...
in which case qualifiers should be placed on the other thing, 
not on Forward Secrecy itself.

An example of LAaFS is the way the Germans used Enigma.
There was, in effect, an ephemeral session key.  It was
the right general idea;  it just wasn't long enough or
random enough.
