AOT: Anonymization by Oblivious Transfer
IACR Cryptol. ePrint Arch., 2021 We introduce AOT, an anonymous communication system based on mix network architecture that uses oblivious transfer (OT) to deliver messages. Using OT to deliver messages helps AOT resist blending ($n-1$) attacks and helps AOT preserve receiver anonymity, even if a covert adversary controls all nodes in AOT.

Ciphertext Obfuscation-based Oblivious Transfer Protocol [PDF]
Jisuanji gongchengThe Oblivious Transfer (OT) protocol is a privacy-preserving two-way communication protocol important for building secure multiparty computations. To exchange symmetric keys, this protocol is typically based on the Rivest—Shamir—Adleman (RSA) or Diffie ...

Quantum XOR and Rabin oblivious transfer [PDF]
, 2023 Oblivious transfer is a cryptographic primitive involving two non-trusting communicating parties. Since it is a basic building block for any two-party computation, it is a quite powerful and important cryptographic functionality and thus topic of ...

Post-Quantum Universal Composable OT Based on Key Exchange
IEEE Access, 2020 We construct a universal composable framework for two-message oblivious transfer protocols based on lattice-assumption. Compared with the paper proposed by Liu and Hu, we modify a framework proposed by Liu and Hu by adding three tools, which are XOR, Bit

Two-Server Oblivious Transfer for Quantum Messages
, 2022 Oblivious transfer is considered as a cryptographic primitive task for quantum information processing over quantum network. Although it is possible with two servers, any existing protocol works only with classical messages.

Breaking barriers in two-party quantum cryptography via stochastic semidefinite programming [PDF]
QuantumIn the last two decades, there has been much effort in finding secure protocols for two-party cryptographic tasks. It has since been discovered that even with quantum mechanics, many such protocols are limited in their security promises. In this work, we

Equivocable Oblivious Transfer [PDF]
, 1996 We analyze and enhance Oblivious Transfer (OT) protocols to accommodate security against adaptive attacks. Previous analysis has been static in nature, treating the security of Alice and the security of Bob as separate cases, determined in advance.

Macromolecular Rapid Communications, EarlyView.The ability of photoacids to increase their acidity in response to light irradiation (excited state proton transfer, ESPT) makes them attractive building blocks for the design of stimuli‐responsive copolymers. In this contribution, we present highly biocompatible polyphotoacids based on poly(2‐oxazoline)s bearing 1‐hydroxypyrene units. Low cytotoxicity,
