This article suggests a new image encryption algorithm based on a secure variant of Hill
Cipher (HC) and three improved one-dimensional (1D) chaotic maps. The proposed scheme …

The conventional symmetric Hill cipher encryption algorithm, applied for data encryption,
presents several disadvantages. However, a drawback of the conventional algorithm is …

In the current high-tech era, the growing popularity of e-healthcare has heightened the
attention focused on data security against cyber-attacks. As digital medical images are …

The Hill cipher is a classical symmetric encryption algorithm that succumbs to the know-
plaintext attack. Although its vulnerability to cryptanalysis has rendered it unusable in …

Secured communication of text information is prime importance across the globe.
Cryptography is one of the methods to attain security. The Hill cipher is a symmetric …

This paper describes an algorithm that uses dynamic programming to order IC tests so that
faulty circuits are detected early in the test sequence and the average test time is minimized …

The Hill cipher is resistant to brute-force and statistical attacks, but it can be broken with a
known plaintext-ciphertext attack (KPCA). In this paper, we propose a modification of the Hill …

In this paper, we will introduce a new color image encryption algorithm. These images are of
arbitrary sizes (n, m). This technique is based on a coupling of two chaotic maps; Namely …

We propose and analyze a new modification of the Hill cipher, HCM-EE, generating dynamic
encryption key matrix by exponentiation that is made efficiently with the help of eigenvalues …

In this paper, it is proved that Lin et al.'s scheme that tried to strengthen the Hill cipher
against the known‐plaintext attack has several security flaws and is vulnerable to the …
