Lattice-based cryptography is the use of conjectured hard problems on point lattices in Rn
as the foundation for secure cryptographic systems. Attractive features of lattice cryptography …

Smart contracts are applications that execute on blockchains. Today they manage billions of
dollars in value and motivate visionary plans for pervasive blockchain deployment. While …

Isogeny-based assumptions have emerged as a viable option for quantum-secure
cryptography. Recent works have shown how to build efficient (public-key) primitives from …

Machine learning (ML) has been widely recognized as an enabler of the global trend of
digital transformation. With the increasing adoption of data-hungry machine learning …

Attribute based encryption (ABE)[13] determines decryption ability based on a user's
attributes. In a multi-authority ABE scheme, multiple attribute-authorities monitor different …

A pseudorandom function F:\mathcalK*\mathcalX→\mathcalY is said to be key homomorphic
if given F (k 1, x) and F (k 2, x) there is an efficient algorithm to compute F (k 1⊕ k 2, x) …

This paper presents Riposte, a new system for anonymous broadcast messaging. Riposte is
the first such system, to our knowledge, that simultaneously protects against traffic-analysis …

We studied 53 privacy-preserving neural-network papers in 2016-2022 based on
cryptography (without trusted processors or differential privacy), 16 of which only use …

We deal with the problem of a center sending a message to a group of users such that some
subset of the users is considered revoked and should not be able to obtain the content of the …

Blockchains are gaining traction and acceptance, not just for cryptocurrencies, but
increasingly as an architecture for distributed computing. In this work we seek solutions that …
