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 …

Signature schemes, proposed in 1976 by Diffie and Hellman, have become ubiquitous
across modern communications. They allow for the exchange of messages from one sender …

Digital signatures are widely used in modern communication to guarantee authenticity and
transferability of messages. The security of currently used classical schemes relies on …

Digital signatures guarantee the authenticity and transferability of messages and are widely
used in modern communication. The security of currently used classical digital signature …

Proactive obfuscation is a new method for creating server replicas that are likely to have
fewer shared vulnerabilities. It uses semantics-preserving code transformations to generate …

Recent years have seen a tremendous growth in the interest in secure multiparty
computation (MPC) and its applications. While much progress has been made concerning …

The ability to know and verifiably demonstrate the origins of messages can often be as
important as encrypting the message itself. Here we present an experimental demonstration …

Quantum digital signatures (QDSs), which distribute and measure quantum states by key
generation protocols and then sign messages via classical data processing, are a key area …

Quantum walks can be applied for some quantum information processing tasks such as
quantum search, element distinctness, state transfer and teleportation. In this paper, we …

Digital signatures are widely used in electronic communications to secure important tasks
such as financial transactions, software updates, and legal contracts. The signature …
