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.

Institutional Environment and the Use of Blockchain Technology: Exploring the Context and Conditions of Using Blockchain in the Higher Education Institutions

open access: yesHigher Education Quarterly, Volume 79, Issue 3, July 2025.
ABSTRACT Blockchain (BC) technology is widely believed to be the next disruptive technology that can address challenges in higher education institutions (HEIs) and support resilient strategies. This study aims to contribute to the literature and inform policymakers about BC's capability and potential in HE by examining enablers, barriers and contextual

Multikey Verifiable Homomorphic Encryption

open access: yesIEEE Access, 2022
A homomorphic encryption (HE) scheme is an advanced encryption technology which allows any user receiving ciphertexts to perform computations over them in a public manner. An important application of an HE scheme is a private delegating computation where

Memristive crypto primitive for building highly secure physical unclonable functions

open access: yesScientific Reports, 2015
Physical unclonable functions (PUFs) exploit the intrinsic complexity and irreproducibility of physical systems to generate secret information. The advantage is that PUFs have the potential to provide fundamentally higher security than traditional ...

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...

High-level Cryptographic Abstractions

open access: yes, 2019
The interfaces exposed by commonly used cryptographic libraries are clumsy, complicated, and assume an understanding of cryptographic algorithms. The challenge is to design high-level abstractions that require minimum knowledge and effort to use while ...

Secure Single-Server Aggregation with (Poly)Logarithmic Overhead

open access: yesIACR Cryptology ePrint Archive, 2020
Secure aggregation is a cryptographic primitive that enables a server to learn the sum of the vector inputs of many clients. Bonawitz et al. (CCS 2017) presented a construction that incurs computation and communication for each client linear in the ...

Physically Unclonable Function Utilizing Stochastic Indirect Exchange Interaction

open access: yesSmall Structures, Volume 6, Issue 6, June 2025.
A physically unclonable function (PUF) utilizes manufacturing variations to create secret keys. This study proposes a spin–orbit torque PUF model based on the Ruderman–Kittel–Kasuya–Yosida interaction. It features near‐ideal properties that can operate under zero magnetic field and varying temperatures.

Cryptanalysis of a Pairing-free Certificateless Signcryption scheme

open access: yesICT Express, 2021
Signcryption is a very useful cryptographic primitive that aims to achieve authentication and confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and Ma (2019) which is claimed to be secure.
