Automatically eliminating speculative leaks from cryptographic code with blade

Proc. ACM Program. Lang., 2020
We introduce Blade, a new approach to automatically and efficiently eliminate speculative leaks from cryptographic code. Blade is built on the insight that to stop leaks via speculative execution, it suffices to cut the dataflow from expressions that ...

Breaking universal limitations on quantum conference key agreement without quantum memory

Communications Physics, 2023
Quantum conference key agreement is an important cryptographic primitive for future quantum network. Realizing this primitive requires high-brightness and robust multiphoton entanglement sources, which is challenging in experiment and unpractical in ...

RRAM Variability Harvesting for CIM‐Integrated TRNG

Advanced Electronic Materials, EarlyView.
This work demonstrates a compute‐in‐memory‐compatible true random number generator that harvests intrinsic cycle‐to‐cycle variability from a 1T1R RRAM array. Parallel entropy extraction enables high‐throughput bit generation without dedicated circuits. This approach achieves NIST‐compliant randomness and low per‐bit energy, offering a scalable hardware

Parallel Algorithm for Approximate State Graph Exploration With Restricted Memory Footprint

Concurrency and Computation: Practice and Experience, Volume 38, Issue 1, January 2026.
ABSTRACT We investigate the performance of algorithms that explore large state graphs of finite state machines without input by following paths. To improve on anchor‐based and candidate‐based explorations and to avoid the performance overhead of full anchor lists and the tuning sensitivity of timeout‐based methods, we propose and analyze exploration ...

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

Computer 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

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

Journal 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 ...
