Cosmology in Coherence-Information Field Theory: Primordial Spectrum, CMB Constraints and Observational Signatures.

Amit Jana

We investigate a cosmological realization of Coherence–Information Field Theory (CIFT) through a coherence field with noncanonical kinetic structure. The framework predicts modified primordial perturbation spectra, reduced sound speed, and distinctive observational signatures in the cosmic microwave background. We derive the perturbation equations, …

Improved Related-Key Differential Attacks against AES-256

Anubhab Baksi, Ajay Das, Smita Das, Patrick Derbez et autres

In this paper, we revisit the differential meet-in-the-middle attack and classical differential attack on AES-256 under the related-key setting, as introduced in Boura et al.'s ToSC 2023 and Song et al.'s Asiacrypt 2024 works. We propose new attacks against 13-round AES-256, all …

Physical Exercise is a Therapy to Reduce Seizure Susceptibility

Amit Jana, Aloke Sen Barman

For the prevention and treatment of epilepsy, neuroprotective and antiepileptogenic treatments have been thoroughly studied. The hopeful impact of the ketogenic diet, a supplemental treatment, on the intestinal microbiota to lessen seizure susceptibility is summarised in this review. The need of exercise …

A Severe Vulnerability and an Effective Defense Against DFA on Ascon

Amit Jana, Debdeep Mukhopadhyay

Differential Fault Attack ( DFA ) is a powerful cryptanalytic technique for recovering cryptographic keys by exploiting computational faults. At Indocrypt 2024, the first DFA on Ascon was introduced using a bit-flip fault model to recover a 64-bit key, followed by a …

Depending on DEEPAND: Cryptanalysis of NLFSR-Based Lightweight Ciphers TinyJAMBU, KATAN, and KTANTAN

Amit Jana, Mostafizar Rahman

Automated cryptanalysis has taken center stage in the arena of cryptanalysis since the pioneering work by Mouhaet al. which showcased the power of Mixed Integer Linear Programming (MILP) in solving cryptanalysis problems that otherwise, required significant effort. Since the inception, research in …

Differential Fault Attack on PHOTON-Beetle

Amit Jana, Goutam Paul

In this paper, we report the first differential fault attack (DFA) on nonce-based AE scheme PHOTON-BEETLE, which is one of the finalists in the ongoing NIST LwC competition. In general, it is a challenging task to perform DFA for any nonce-based sponge …
