Elliptic Curve Cryptography (ECC) is a relatively recent branch of cryptography based on the
arithmetic of elliptic curves and the Elliptic Curve Discrete Logarithm Problem (ECDLP) …

Chaotic systems are suitable for protecting digital images due to many of their own
characteristics. However, many chaos-based image colour encryption algorithms exhibit …

Securing critical infrastructures and manufacturing plants in the Industrial-Internet-Of-Things
and Industry 4.0 is a challenge today due to the increased number of attacks against …

Most of the image encryption schemes based on chaos have so far employed symmetric key
cryptography, which leads to a situation where the key cannot be transmitted in public …

Abstract The Hybrid Public Key Encryption (HPKE) scheme is an emerging standard
currently under consideration by the Crypto Forum Research Group (CFRG) of the IETF as a …

Cryptographic algorithms are vital components ensuring the privacy and security of
computer systems. They have constantly improved and evolved over the years following …

Instruction set randomization (ISR) was proposed early in the last decade as a
countermeasure against code injection attacks. However, it is considered to have lost its …

Encryption method is an effective way to guarantee the confidentiality and in other ways
(digital signature) the authenticity of data. The use of the digital signature derives from the …

Public key cryptography is used to asymmetrically establish keys, authenticate or encrypt
data between communicating parties at a relatively high performance cost. To reduce …
