Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …

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 …

In the classical model of computation, it is well established that one-way functions (OWF) are
minimal for computational cryptography: They are essential for almost any cryptographic …

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 …

Timed-release encryption is a kind of encryption scheme in which a recipient can decrypt
only after a specified amount of time T (assuming that we have a moderately precise …

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 …

Given a ciphertext, is it possible to prove the deletion of the underlying plaintext? Since
classical ciphertexts can be copied, clearly such a feat is impossible using classical …
