Key schedule algorithm is one of the core elements that significantly affect the security of an
encryption algorithm. While its importance is undeniable, the key schedule algorithm has not …

We evaluate the security of RECTANGLE from the perspective of actual key information
(AKI). Insufficient AKI permits the attackers to deduce some subkey bits from some other …

The key schedule algorithm (KSA) is a crucial element of symmetric block ciphers with a
direct security impact. Despite its undeniable significance, the KSA is still a less focused …

The key schedule, an essential part of the cipher (cryptography), is often neglected during
the cipher algorithm design. However, a compromised key schedule leads to the entire …

In this paper, we analyze the randomness of the RECTANGLE cipher. RECTANGLE is a
lightweight block cipher with 64-bit block size and variants key lengths of 80 and 128 bits …

The lightweight block cipher PRESENT has become viable for areas like IoT (Internet of
Things) and RFID tags, due to its compact design and low power consumption, while …

The key schedule function in Rijndael block cipher did not receive the same amount of
attention during design as the cipher components. Based on our research, there are several …

The success and safety of block cipher systems heavily depend on how efficient and secure
their Key Schedule Algorithms (KSAs) are, especially when fighting against cryptanalytic …

In this paper, a new key scheduling technique termed MSBK is proposed that introduces the
split-radix butterfly architecture of fast Fourier transformation (FFT) in the area of …

A key scheduling algorithm is the mechanism that generates and schedules all session-keys
for the encryption and decryption process. The key space of conventional key schedule …
