Compact and Simple RLWE Based Key Encapsulation Mechanism
2019In 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 .

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 performGorjan Alagic +6 more

Kurosawa-Desmedt Key Encapsulation Mechanism, Revisited
2014While 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).

A Key Encapsulation Mechanism for NTRU
2005In this article we present a key encapsulation mechanism (KEM) for NTRU. The KEM is more efficient than a naive approach based on NAEP and resistant against the decryption failures that may occur when using NTRU. We also introduce plaintext awareness for KEMs and use it to tighten a security result by Dent.

LizarMong: Excellent Key Encapsulation Mechanism Based on RLWE and RLWR
2020The RLWE family algorithms submitted to the NIST post-quantum cryptography standardization process have each merit in terms of security, correctness, performance, and bandwidth. However, there is no splendid algorithm in all respects. Besides, various recent studies have been published that affect security and correctness, such as side-channel attacks ...

Memory-Tight Reductions for Practical Key Encapsulation Mechanisms
2020The 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
2023A 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 ...

SaberX4: High-Throughput Software Implementation of Saber Key Encapsulation Mechanism
2019 IEEE 37th International Conference on Computer Design (ICCD), 2019Saber is a module lattice-based CCA-secure key encapsulation mechanism (KEM) which has been shortlisted for the second round of NIST's Post Quantum Cryptography Standardization project. To attain simplicity and efficiency on constrained devices, the Saber algorithm is serial by construction.
