Achieving the physical limits of the bounded-storage model [PDF]

open access: yes, 2011
Secure two-party cryptography is possible if the adversary's quantum storage device suffers imperfections. For example, security can be achieved if the adversary can store strictly less then half of the qubits transmitted during the protocol.

Delegating a Product of Group Exponentiations with Application to Signature Schemes (Submission to Special NutMiC 2019 Issue of JMC)

open access: yesJournal of Mathematical Cryptology, 2020
Many public-key cryptosystems and, more generally, cryptographic protocols, use group exponentiations as important primitive operations. To expand the applicability of these solutions to computationally weaker devices, it has been advocated that a ...

Portable PGAS‐Based GPU‐Accelerated Branch‐And‐Bound Algorithms at Scale

open access: yesConcurrency and Computation: Practice and Experience, Volume 37, Issue 25-26, 30 November 2025.
ABSTRACT The Branch‐and‐Bound (B&B) technique plays a key role in solving many combinatorial optimization problems, enabling efficient problem‐solving and decision‐making in a wide range of applications. It incrementally constructs a tree by building candidates to the solutions and abandoning a candidate as soon as it determines that it cannot lead to ...

Variable Bit Permutations: Linear Characteristics and Pure VBP-Based Cipher [PDF]

open access: yesComputer Science Journal of Moldova, 2005
This paper describes linear characteristics of the variable bit permutations (VBP) that are used in the form of the data-dependent permutations. This primitive suites well to the design of fast cheap-hardware-oriented ciphers. Because of the existence of

Hardware Design for Secure Telemedicine Using A Novel Framework, A New 4D Memristive Chaotic Oscillator, and Dispatched Gray Code Scrambler

open access: yesEngineering Reports, Volume 7, Issue 10, October 2025.
This work presents a secure telemedicine cryptosystem based on a novel 4D memristive chaotic oscillator and a Dispatched Gray Code Scrambler (DGCS). Implemented on FPGA, the system ensures power‐efficient encryption, making it suitable for real‐time medical image transmission in IoT healthcare environments.

One-time memory from isolated Majorana islands

open access: yesNew Journal of Physics, 2022
A one-time memory (OTM) stores two bits such that either bit can be retrieved, but not both. One-time memories have been shown to allow for secure classical and quantum computations.

Open and Closed Loop Approaches for Energy Efficient Quantum Optimal Control

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 10, October 2025.
Concepts from quantum thermodynamics and optimal control are blended to derive a theoretical framework to quantify and minimize the energetic cost of a pulse for unitary synthesis. Two complementary techniques (based on GRAPE and Reinforce‐DRL) are implemented as open‐source software that co‐optimizes the fidelity and energetic cost within quantum ...
