Cryptography and Information Security (CIS) Seminar

Silas Richelson: Topology-Hiding Computation
Friday, February 13, 2015 - 10:30am to 12:00pm

Abstract: 

Vanishree Rao: Adaptive Multiparty Non-Interactive Key Exchange without Setup in the Standard Model
Friday, January 23, 2015 - 10:30am to 12:00pm

Abstract: Non-interactive key exchange (NIKE) is a fundamental notion in Cryptography. This notion was introduced by Diffie and Hellman in 1976.

Raphael Bost: Machine Learning Classification over Encrypted Data
Friday, February 6, 2015 - 10:30am to 12:00pm

Abstract:  Machine learning classification is used in numerous settings nowadays, such as medical or genomics predictions, spam detection, face recognition, and financial predictions.

Breaking a real life signature scheme with only 20 signature queries
Thursday, October 30, 2014 - 4:00pm to 5:30pm

Abstract: I will discuss recent joint work with Uni. Adelaide on
applying the Flush+Reload side channel to the OpenSSL implementation
of EC-DSA. The attacks require side-channel analysis as well as
the lattice based cryptanalysis of DSA nonces introduced by

Obfuscating Circuits via Composite-Order Graded Encoding
Friday, October 31, 2014 - 10:30am to 12:00pm
Abstract:
 
On the Communication Complexity of Secure Function Evaluation with Long Output
Friday, November 14, 2014 - 10:30am to 12:00pm

Abstract: We study the communication complexity of secure function evaluation (SFE).

Dual System Encryption via Predicate Encodings
Friday, November 7, 2014 - 10:30am to 12:00pm
Abstract:

In this talk, I will present the notion of predicate encodings, an
information-theoretic primitive reminiscent of linear secret-sharing
that in addition, satisfies a novel notion of reusability. Using this
notion, we obtain a unifying framework for adaptively-secure
Strong Key Derivation from Noisy Sources
Friday, December 12, 2014 - 10:30am to 12:00pm
Abstract:  A shared cryptographic key enables strong authentication.  Candidate sources for creating such a shared key include biometrics and physically unclonable functions.  However, these sources come with a substan
Sergey Gorbunov: New Advances in Fuctional Encryption
Friday, October 10, 2014 - 10:30am to 12:00pm

Abstract: Functional encryption is an emerging vision for public-key cryptography offering fine-grained mechanism for computing on encrypted data.  Unfortunately, currently all of the more powerful constructions of functional encryption are built from non
