RLizard: Post-Quantum Key Encapsulation Mechanism for IoT Devices [PDF]

IEEE Access, 2019
We propose the RLizard key encapsulation mechanism (KEM), whose security depends on the ring learning with errors and ring learning with rounding problems.

Modelling and verification of post-quantum key encapsulation mechanisms using Maude [PDF]

PeerJ Computer Science, 2023
Communication and information technologies shape the world’s systems of today, and those systems shape our society. The security of those systems relies on mathematical problems that are hard to solve for classical computers, that is, the available current computers.

Cca-Secure Key Encapsulation Mechanism Based on Factoring Assumption [PDF]

Tatra Mountains Mathematical Publications, 2012
ABSTRACT In this article a key encapsulation mechanism is presented which is based on squaring function, where the input element is from QR+N, where QR+N denotes the signed quadratic residue group, and N is a Blum integer.

Module-Lattice-Based Key-Encapsulation Mechanism Standard

, 2023
A key-encapsulation mechanism (or KEM) is a set of algorithms that, under certain conditions, can be used by two parties to establish a shared secret key over a public channel. A shared secret key that is securely established using a KEM can then be used with symmetric-key cryptographic algorithms to perform basic tasks in secure communications, such ...

A Key Encapsulation Mechanism from Low Density Lattice Codes [PDF]

Key Encapsulation Mechanisms (KEMs) are a set of cryptographic techniques that are designed to provide symmetric encryption key using asymmetric mechanism (public key). In the current study, we concentrate on design and analysis of key encapsulation mechanism from low density lattice codes (KEM-LDLC) to go down the key size by keeping an acceptable ...

A Practical Key-Recovery Attack on LWE-Based Key-Encapsulation Mechanism Schemes Using Rowhammer

Physical attacks are serious threats to cryptosystems deployed in the real world. In this work, we propose a microarchitectural end-to-end attack methodology on generic lattice-based post-quantum key encapsulation mechanisms to recover the long-term secret key.

Compact and Simple RLWE Based Key Encapsulation Mechanism

, 2019
In this paper, we propose a key encapsulation scheme based on NewHope and Kyber, two NIST post-quantum standardization project candidates. Our scheme is based on NewHope, thus it is simple and has fast implementation while it is making use of smaller key sizes and easily changeable security level advantages of Kyber .

Comparison of security arguments of promising key encapsulation mechanisms

Радіотехніка, 2022
Исследование механизмов инкапсуляции ключей на алгебраических решетках является одним из важных направлений в современной постквантовой криптографии, поскольку многие механизмы уже либо стандартизированы (ANSI X.9.98, ДСТУ 8961:2019 “Скеля” ), либо являются перспективными кандидатами на стандартизацию (CRYSTALS-Kyber, FrodoKEM).

On Constructing Dynamic and Forward Secure Authenticated Group Key Agreement Scheme from Multikey Encapsulation Mechanism [PDF]

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.
