Comparative Analysis of Key Encapsulation Mechanisms

2019 10th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems: Technology and Applications (IDAACS), 2019
The paper deals with the possible comparative analysis methods of the cryptographic primitives' properties. Methods of comparative analysis – analytic hierarchy process and variations of weight indices methods are investigated and analyzed. Conclusions are made and recommendations on the use of the cryptographic primitives' estimation methods are ...

Generic Certificateless Key Encapsulation Mechanism

2007
We propose the first generic construction of certificateless key encapsulation mechanism (CL-KEM) in the standard model, which is also secure against malicious-but-passive KGC attacks. It is based on an ID-based KEM, a public key encryption and a message authentication code.

Public Verifiable Key Encapsulation Mechanism under Factoring

2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013
The cipher text consistency check that can be implemented publicly has practical significance, and it is always an interested studying aspect to construct cryptographic algorithm without pairings in the field of cryptographic. On the other hand, it is one of the most important research topics to design CCA-secure PKE schemes with weaker assumptions ...

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 .

Key Encapsulation Mechanism from Multilinear Maps

2017
The key encapsulation mechanism (KEM) and the data encapsulation mechanism (DEM) form a hybrid encryption, which effectively solves the problem of low efficiency of public key cryptography and key distribution problems in symmetric encryption system.

Recommendations for key-encapsulation mechanisms

A key-encapsulation mechanism (KEM) is a set of algorithms that can be used by two par-ties under certain conditions to securely establish a shared secret key over a public channel. A shared secret key that is established using a KEM can then be used with symmetric-key cryptographic algorithms to perform

Kurosawa-Desmedt Key Encapsulation Mechanism, Revisited

2014
While the hybrid public key encryption scheme of Kurosawa and Desmedt (CRYPTO 2004) is provably secure against chosen ciphertext attacks (namely, IND-CCA-secure), its associated key encapsulation mechanism (KEM) is not IND-CCA-secure (Herranz et al. 2006, Choi et al. 2009).

Hybrid Key Encapsulation Mechanisms and Authenticated Key Exchange

2019
Concerns about the impact of quantum computers on currently deployed public key cryptography have instigated research into not only quantum-resistant cryptographic primitives but also how to transition applications from classical to quantum-resistant solutions.

Memory-Tight Reductions for Practical Key Encapsulation Mechanisms

2020
The efficiency of a black-box reduction is an important goal of modern cryptography. Traditionally, the time complexity and the success probability were considered as the main aspects of efficiency measurements. In CRYPTO 2017, Auerbach et al. introduced the notion of memory-tightness in cryptographic reductions and showed a memory-tight reduction of ...

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 ...
