Ad Hoc Multi-Input Functional Encryption

Shweta Agrawal, Michael Clear, Ophir Frieder, Sanjam Garg, Adam O'Neill, Justin Thaler, Michael Wagner
2020 Innovations in Theoretical Computer Science  
At a technical level, our results are obtained by combining standard MIFE schemes and two-round secure multiparty computation (MPC) protocols in novel ways highlighting an interesting interplay between  ...  MIFE and two-round MPC.  ...  While security appears to follow intuitively from the security of MPC, FE and MIFE, the proof must contend with several technical hurdles as we are forced to deal with indistinguishability style security  ...

WYS*: A DSL for Verified Secure Multi-party Computations [article]

Aseem Rastogi, Nikhil Swamy, Michael Hicks
2018 arXiv   pre-print
We have implemented several MPC protocols in Wys*, including private set intersection, joint median, and an MPC card dealing application, and have verified their correctness and security.  ...  Wys* source programs are essentially F* programs written in a custom MPC effect, meaning that the programmers can use F*'s logic to verify the correctness and security properties of their programs.  ...  The pre-and postcondition specifications on the combinators encode a program logic for MPC.  ...

of obfuscation -similar to how the Universal Composition framework unifies various multi-party computation tasks like commitment, coin-tossing and zero-knowledge proofs.  ...  Highlights of our framework include the following: • We use a new indistinguishability preserving (IND-PRE) definition of security that interpolates indistinguishability and simulation style definitions  ...  Note that on obtaining handles for various agents from B[Σ], S hands over dummy ciphertexts to Adv, and if Adv gives them back to S, it translates them back to the handles.  ...

Multiparty computation secure against continual memory leakage

Elette Boyle, Shafi Goldwasser, Abhishek Jain, Yael Tauman Kalai
2012 Proceedings of the 44th symposium on Theory of Computing - STOC '12  
Our result relies on standard cryptographic assumptions, and our security parameter is polynomially related to the number of parties.  ...  We construct a multiparty computation (MPC) protocol that is secure even if a malicious adversary, in addition to corrupting 1-fraction of all parties for an arbitrarily small constant > 0, can leak information  ...  All parties engage in an execution of the (standard) MPC protocol MPC(FE 1 ,...,Em,crs) to collectively compute the randomized functionality FE 1 ,...  ...

We also calculate three new distances to M74 of 9.6+/-2.8 Mpc, 7.7+/-1.7 Mpc and 9.6+/-2.2 Mpc.  ...  When combined with existing kinematic and BSM distance estimates, we derive a mean value of 9.3+/-1.8 Mpc.  ...  A weighted average yields a value of D = 9.6 ± 2.8 Mpc. This error is statistical and comes from combining the uncertainties of each parameter in the SCM equations.  ...
