Hi All -
Finally the reading group is on the road. This monday, Oct 17, 9-10:30am, 
Adam Oneil will speak about functional encryption., or in his words:

We overview the recent notion of functional encryption (FE), a concept 
first developed in the pioneering work on Fuzzy Identity-Based Encryption 
(Sahai and Waters, Eurocrypt 2005).  At a high level, FE associates secret 
keys with *functions*, whereby a secret key sk_f for a function f 
``decrypts'' an encryption c of m to f(m).

Although we will discuss the state-of-the-art constructions, particular 
emphasis will be given to understanding definitional aspects of FE rather 
than proof techniques.  Indeed, a fascinating aspect of FE is that properly 
formulating its security is quite non-trivial, and a semantic security 
style formulation of security turns out to be *inequivalent* to an 
indistinguishability style one (in contrast to the classical setting of 
public-key encryption).

We'll meet at room 137 at the CS building, BU (111 Cummington st).
At this time there is usually plenty of (metered) street parking on 
Cummington st. Also if you need a shuttle from MIT/MSR/wherever please let 
me know.


PS - Please also feel free to go to
and either add papers that you would like to see presented at the reading 
group, or comment on exisitng suggestions. Also volunteering to present a 
paper will be highly appreciated!
