Public Key Protocols from Twisted-Skew Group Rings
CryptographyThis article studies some algebraic structures known as twisted-skew group rings in the context of public key cryptography. We first present some background related to these structures to then specifically introduce particular twisted-skew group rings ...

Certificateless Deniable Authenticated Encryption for Location-Based Privacy Protection
IEEE Access, 2019 Deniable authenticated encryption (DAE) is a cryptographic primitive that supports data confidentiality with deniable authentication in an efficient manner. The DAE plays a significant role in location-based service systems for privacy protection.

Secure Cryptographic Key Encapsulation and Recovery Scheme in Noisy Network Conditions
Applied SciencesIn this study, we present the Response-Based Key Encapsulation Mechanism (R-KEM), an ephemeral key encapsulation and recovery scheme tailored for cryptographic systems in high-noise, high-jamming network environments.

A Concrete LIP-Based KEM With Simple Lattices
IEEE AccessRecent developments have been made in the construction of cryptosystems with security based on the hardness of the lattice isomorphism problem (LIP). Due to lattice conjectures, one may expect in the future that breaking such schemes is computationally ...

Comparison of security arguments of promising key encapsulation mechanisms
Radiotekhnika, 2022 The study of key encapsulation mechanisms on algebraic lattices is one of the important directions in modern post-quantum cryptography, since many mechanisms are already either standardized (ANSI X.9.98, DSTU 8961:2019 "Skelya") or are promising candidates for standardization (CRYSTALS-Kyber, FrodoKEM).

A provably masked implementation of BIKE Key Encapsulation Mechanism
IACR Communications in CryptologyBIKE is a post-quantum key encapsulation mechanism (KEM) selected for the 4th round of the NIST's standardization campaign. It relies on the hardness of the syndrome decoding problem for quasi-cyclic codes and on the indistinguishability of the public key from a random element, and provides the most competitive performance among round 4 candidates ...

The Scientific World Journal, 2015 The approach of instantiating authenticated group key exchange (GAKE) protocol from the multikey encapsulation mechanism (mKEM) has an important advantage of achieving classical requirement of GAKE security in one communication round.

IEEE AccessCryptographic protocols can be used to covertly exchange information without arousing suspicion. The covert channels created in this way are called subliminal channels. In this work, three different subliminal channels using CRYSTALS-Kyber are discovered.

MATHEMATICAL ANALYSIS OF QC-MDPC STRUCTURES IN BIKE V5.2 POST-QUANTUM KEY ENCAPSULATION SCHEME
BarekengThe security of the BIKE scheme depends on a complex mathematical structure built upon QC-MDPC codes. This scheme is constructed using the Niederreiter framework and the application of transformation. Its security is based on the complexity of two main

Post-Quantum Secure Multi-Factor Authentication Protocol for Multi-Server Architecture
EntropyThe multi-factor authentication (MFA) protocol requires users to provide a combination of a password, a smart card and biometric data as verification factors to gain access to the services they need.
