We present the digital signature scheme, MQ-Sign, based on UOV whose security relies on
the hardness of solving large systems of multivariate quadratic equations. MQ-Sign supports …

Quantum computing increases the security risks of data in intelligent Internet of Things (IoT)
based on traditional cryptography. Multivariate Public Key Cryptography has the security …

Abstract Smart Connected Health Systems (SCHSs) belong to health systems that provide
services of health care remotely. They provide the doctors with access to electronic medical …

Abstract Post-Quantum Cryptography (PQC) is rapidly develo** as a stable and reliable
quantum-resistant form of cryptography, throughout the industry. Similarly to existing …

Abstract The Internet of Medical Things (IoMTs) are the group of medical devices connected
to Internet, to perform the processes and services that support healthcare. The amount of …

Multivariate signature belongs to Multivariate-Quadratic-Equations Public Key Cryptography
(MPKC), which is secure to quantum computer attacks. Compared with RSA and ECC, it is …

Asymmetric cryptography plays an essential role in many areas, including cloud computing,
big data, blockchain, and the Internet of Things (IoT). However, most of them are based on …

UOV and Rainbow are multivariate signature schemes, which are known to be efficient and
secure enough against known attacks under suitable parameter selections, and have been …

Multivariate quadratic equations (MQ)-based public-key cryptographic algorithms are one of
promising post-quantumreplacements for currently used public-key cryptography. After …
