ZkHybridChain: ultra-efficient cross-border credit recognition

Frontiers in Blockchain
BackgroundCross-border credit recognition in Sino-Foreign Cooperative Education (SFCE) suffers from data fragmentation, regulatory conflicts (e.g., GDPR vs. China’s Data Security Law), and low efficiency.ObjectiveThis paper proposes ZkHybridChain, a dual-

Development of a New Post-Quantum Digital Signature Algorithm: Syrga-1

Computers
The distinguishing feature of hash-based algorithms is their high confidence in security. When designing electronic signature schemes, proofs of security reduction to certain properties of cryptographic hash functions are used.

Fully Quantum Hash Function

We introduce a novel, \textit{fully} quantum hash (FQH) function within the quantum walk on a cycle framework. We incorporate deterministic quantum computation with a single qubit to replace classical post-processing, thus increasing the inherent security. Further, our proposed hash function exhibits zero collision rate and high reliability. We further

A family of quantum codes with performances close to the hashing bound under iterative decoding

, 2013
International audienceWe propose here a new construction of quantum codes combining an improved version of a family of spatially coupled quantum LDPC codes, suggested in [1], with a family of error reducing turbo-codes of [2].

Improved Quantum Rebound Attacks on Double Block Length Hashing with Round-Reduced AES-256 and ARIA-256

IACR Transactions on Symmetric Cryptology
At EUROCRYPT 2020, Hosoyamada and Sasaki proposed the first dedicated quantum collision attacks on hash functions. Their proposal presented a quantum adaptation of the rebound attack and revealed that differential trails, which have too low probability ...

Cryptographic quantum hashing [PDF]

, 2014
We present a version of quantum hash functions based on non-binary discrete functions. The proposed quantum procedure is 'classical-quantum', that is, it takes a classical bit string as an input and produces a quantum state.

Lightening CROSS: Memory Optimized Implementations of CROSS

Transactions on Cryptographic Hardware and Embedded Systems
Digital signature schemes derived from non-interactive zero-knowledge (NIZK) proofs are rapidly gaining prominence within post-quantum cryptography. CROSS is a promising new code-based post-quantum digital signature scheme based on the NIZK framework ...
