Modified Hill Cipher Algorithm using Myszkowski Transposition to address Known-Plaintext attack

International Journal for Research in Applied Science and Engineering Technology, 2022
: Hill Cipher algorithm is a Polygraphic cipher known to be vulnerable to the Known-Plaintext attack. It is a type of attack wherein the attacker has access to a pair of Plaintext and Ciphertext. Possible leaked information can be used to reveal critical

Matrix computation over homomorphic plaintext-ciphertext and its application [PDF]

Tongxin xuebao
Those homomorphic encryption schemes supporting single instruction multiple data (SIMD) operations effectively enhance the amortized efficiency of ciphertext computations, yet the structure of ciphertexts leads to high complexity in matrix operations.In ...

Simpler and Faster BFV Bootstrapping for Arbitrary Plaintext Modulus from CKKS [PDF]

IACR Cryptology ePrint Archive
Bootstrapping is currently the only known method for constructing fully homomorphic encryptions. In the BFV scheme specifically, bootstrapping aims to reduce the error of a ciphertext while preserving the encrypted plaintext.

Low-Cost Security of IoT Sensor Nodes With Rakeness-Based Compressed Sensing: Statistical and Known-Plaintext Attacks [PDF]

IEEE Transactions on Information Forensics and Security, 2018
Compressed sensing has been proposed to both yield low-cost compression and low-cost encryption. This can be very useful in the design of sensor nodes with a limited resource budget whose acquisition must be kept as private as possible.

ROBin: Known-Plaintext Attack Resistant Orthogonal Blinding via Channel Randomization [PDF]

IEEE Conference on Computer Communications, 2020
Orthogonal blinding based schemes for wireless physical layer security aim to achieve secure communication by injecting noise into channels orthogonal to the main channel and corrupting the eavesdropper’s signal reception. These methods, albeit practical,

Key-Dependent Feedback Configuration Matrix of Primitive σ–LFSR and Resistance to Some Known Plaintext Attacks

IEEE Access, 2022
In this paper, we propose and evaluate a method for generating key-dependent feedback configurations (KDFC) for $\sigma $ -LFSRs. $\sigma $ -LFSRs with such configurations can be applied to any stream cipher that uses a word-based LFSR.
