Quantum cryptography is the art and science of exploiting quantum mechanical effects in
order to perform cryptographic tasks. While the most well-known example of this discipline is …

We introduce a novel generic ring signature construction, called DualRing, which can be
built from several canonical identification schemes (such as Schnorr identification) …

Fully homomorphic encryption is an encryption method with the property that any
computation on the plaintext can be performed by a party having access to the ciphertext …

MiniQCrypt is a world where quantum-secure one-way functions exist, and quantum
communication is possible. We construct an oblivious transfer (OT) protocol in MiniQCrypt …

We prove that quantum-hard one-way functions imply simulation-secure quantum oblivious
transfer (QOT), which is known to suffice for secure computation of arbitrary quantum …

We present a new scheme for quantum homomorphic encryption which is compact and
allows for efficient evaluation of arbitrary polynomial-sized quantum circuits. Building on the …

We construct a constant-round zero-knowledge classical argument for NP secure against
quantum attacks. We assume the existence of Quantum Fully-Homomorphic Encryption and …

The cryptographic task of secure multi-party (classical) computation has received a lot of
attention in the last decades. Even in the extreme case where a computation is performed …

Quantum cybersecurity is the study of all facets regarding the security of communication and
computation in a distributed network. Significant developments in quantum technologies …

We show how to obfuscate pseudo-deterministic quantum circuits, assuming the quantum
hardness of learning with errors (QLWE) and post-quantum virtual black-box (VBB) …
