Identification Schemes from Key Encapsulation Mechanisms
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 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.

Scabbard: a suite of efficient learning with rounding key-encapsulation mechanisms
IACR Transactions on Cryptographic Hardware and Embedded Systems, 2021 In this paper, we introduce Scabbard, a suite of post-quantum keyencapsulation mechanisms. Our suite contains three different schemes Florete, Espada, and Sable based on the hardness of module- or ring-learning with rounding problem. In this work, we first show how the latest advancements on lattice-based cryptographycan be utilized to create new ...

Stateful KEM: Towards Optimal Robust Combiner for Key Encapsulation Mechanism [PDF]
, 2021 A $(1,n)$-robust combiner combines $n$ cryptography primitives to construct a new primitive of the same type, and guarantees that if any of the ingredient primitive is secure, then the resulting primitive is secure.

Homomorphic-Policy Attribute-Based Key Encapsulation Mechanisms [PDF]
, 2017 Attribute-Based Encryption (ABE) allows to target the recipients of a message according to a policy expressed as a predicate among some attributes. Ciphertext-policy ABE schemes can choose the policy at the encryption time.In this paper, we define a new property for ABE: homomorphic-policy.

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).
