A Secure and Efficient Framework for ECG Signal Digitization and Encryption for Internet of Medical Things Applications. [PDF]
Healthc Technol LettThis paper proposes a secure electrocardiogram (ECG)‐processing framework that digitises ECG waveforms from clinical paper or image‐based records and encrypts them using a dual chaotic cryptographic scheme. The method supports both extracted and native digital signals, ensuring strong security and interoperability for Internet of Medical Things ...

Post-Quantum and Code-Based Cryptography—Some Prospective Research Directions
Cryptography, 2021 Cryptography has been used from time immemorial for preserving the confidentiality of data/information in storage or transit. Thus, cryptography research has also been evolving from the classical Caesar cipher to the modern cryptosystems, based on ...

The Computer JournalAbstract A compression cryptosystem is a single coding process, the output of which is both reduced in space and secure against unauthorized decoding. Considering both Huffman and arithmetic coding, this paper proposes to apply repeatedly minor changes to the compression model, with negligible deterioration of its optimality.

CRYPTANALYSIS OF HYBRID CRYPTOSYSTEMS [PDF]
International Journal of Bifurcation and Chaos, 2013 An essential issue for the validation of ciphers is cryptanalysis, that is, the study of attacks in order to reveal possible weaknesses. In this paper, we propose a systematic and unified methodology for cryptanalyzing known chaos-based cryptosystems borrowed from the open literature, namely shift keying, discrete parameter modulation, switched ...

On McEliece-Type Cryptosystems Using Self-Dual Codes With Large Minimum Weight
IEEE Access, 2023 One of the Round 3 Finalists in the NIST post-quantum cryptography call is the Classic McEliece cryptosystem. Although it is one of the most secure cryptosystems, the large size of its public key remains a practical limitation. In this work, we propose a

Concurrency and Computation: Practice and Experience, Volume 38, Issue 15, August 2026.ABSTRACT This paper presents MusicoCrypt, a context‐bound music‐modulated stream‐encryption framework that incorporates audio‐derived public side information into a pseudorandom‐function‐centered encryption workflow. A shared reference recording is processed using a pitch‐tracking pipeline, and ordered note pairs are encoded as residues in ℤ132 ...

On Matrix‐Based Cryptography Using Matrix Norm and Special Integer Sequences
Mathematische Nachrichten, Volume 299, Issue 8, Page 2087-2102, August 2026.ABSTRACT In this paper, a novel matrix‐based encryption approach based on the Affine Hill cipher is presented. The key matrix is constructed using the Narayana integer sequence, and the Frobenius norm of the key matrix is used as a scaling factor in the key construction.

A McEliece cryptosystem using permutation codes
Journal of Mathematical CryptologyThis paper is an attempt to build a new public-key cryptosystem, similar to the McEliece cryptosystem, using permutation error-correcting codes. We study a public-key cryptosystem built using two permutation error-correcting codes.
