The concept of the “metaverse” has garnered significant attention recently, positioned as the
“next frontier” of the internet. This emerging digital realm carries substantial economic and …

Abstract Wireless Sensor Networks (WSNs) are used in many applications in military,
ecological, and health-related areas. These applications often include the monitoring of …

We present a new 128-bit block cipher called Camellia. Camellia supports 128-bit block size
and 128-, 192-, and 256-bit keys, ie, the same interface specifications as the Advanced …

Wireless sensor networks (WSNs) have recently attracted a lot of interest in the research
community due their wide range of applications. Due to distributed nature of these networks …

Cryptographic algorithms play an important role in the security architecture of wireless
sensor networks (WSNs). Choosing the most storage-and energy-efficient block cipher is …

Substitution boxes (S-box) with strong and secure cryptographic properties are widely used
for providing the key property of nonlinearity in block ciphers. This is critical to be resistant to …

Recently, computer architectures that combine a reconfigurable (or retargetable)
coprocessor with a general-purpose microprocessor have been proposed. These …

This paper studies the security of the block ciphers ARIA and Camellia against impossible
differential cryptanalysis. Our work improves the best impossible differential cryptanalysis of …

Being as unique nonlinear components of block ciphers, substitution boxes (S-boxes)
directly affect the security of the cryptographic systems. It is important and difficult to design …
