Understanding and Constructing AKE via Double-Key Key Encapsulation Mechanism [PDF]

open access: yesLecture Notes in Computer Science, 2018
Motivated by abstracting the common idea behind several implicitly authenticated key exchange (AKE) protocols, we introduce a primitive that we call double-key key encapsulation mechanism (2-key KEM). It is a special type of KEM involving two pairs of secret-public keys and satisfying some function and security property.

Identification Schemes From Key Encapsulation Mechanisms

open access: yesLecture Notes in Computer Science, 2011
We propose a generic way for deriving an identification (ID) scheme secure against concurrent man-in-the-middle attacks from a key encapsulation mechanism (KEM) secure against chosen ciphertext attacks on one-wayness (oneway-CCA). Then we give a concrete one-way-CCA secure KEM based on the Computational Diffie-Hellman (CDH) assumption.

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.

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.
