An efficient lattice-based conditional privacy-preserving group signature with user-controlled and sequential linkability

Cybersecurity
Currently, existing group signature schemes with user-controlled and sequential linkability (GS-UCSL) suffer from critical limitations: they lack post-quantum security, cannot efficiently revoke malicious signers, grant excessive tracing power to group ...

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.

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 ...

Computing quantum hashing in the model of quantum branching programs

, 2020
© 2018 Author(s). We investigate the branching program complexity of quantum hashing. We consider a quantum hash function that maps elements of a finite field into quantum states.

Does Quantum Mechanics Breed Larger, More Intricate Quantum Theories? The Case for Experience-Centric Quantum Theory and the Interactome of Quantum Theories

We pose and address the radical question of whether quantum mechanics, known for its firm internal structure and enormous empirical success, carries in itself the genomes of larger quantum theories that have higher internal intricacy and phenomenological
