It is widely accepted that higher-order masking is a sound countermeasure to protect implementations of block ciphers against side-channel attacks. The main issue while designing s...

Implementations of white-box cryptography aim to protect a secret key in a white-box environment in which an adversary has full control over the execution process and the entire en...

The security of many cryptographic schemes has been based on special instances of the Learning with Errors (LWE) problem, e.g., Ring-LWE, LWE with binary secret, or LWE with ternar...

It is a well-known result that homomorphic encryption is not secure against adaptive chosen ciphertext attacks (CCA2) because of its malleability property. Very recently, however, ...

We introduce the notion of an Extremely Lossy Function (ELF). An ELF is a family of functions with an image size that is tunable anywhere from injective to having a polynomial-siz...

We initiate the study of a proof system model that naturally combines two well-known models: interactive proofs (IPs) and probabilistically-checkable proofs (PCPs). An interactive...

Known methods for obfuscating a circuit need to represent the circuit as a branching program and then use a multilinear map to encrypt the branching program. Multilinear maps are,...
