Post-Quantum Variants of ISO/IEC Standards: Compact Chosen Ciphertext Secure Key Encapsulation Mechanism from Isogenies
Post-quantum cryptosystems Isogeny-based cryptosystems CSIDH
2019/9/17
ISO/IEC standardizes several chosen ciphertext-secure key encapsulation mechanism (KEM) schemes in ISO/IEC 18033-2. However, all ISO/IEC KEM schemes are not quantum resilient. In this paper, we introd...
CCA-Secure Leakage-Resilient Identity-Based Key-Encapsulation from Simple (not $\mathtt{q}$-type) Assumptions
public-key cryptography leakage-resilient identity-based encryption
2019/8/30
In this paper, we propose a new leakage-resilient identity-based encryption (IBE) scheme that is secure against chosen-ciphertext attacks (CCA) in the bounded memory leakage model. It is the first CCA...
SIKE'd Up: Fast and Secure Hardware Architectures for Supersingular Isogeny Key Encapsulation
SIKE post-quantum cryptography isogeny-based cryptography FPGA
2019/6/19
In this work, we present a fast parallel architecture to perform supersingular isogeny key encapsulation (SIKE). We propose and implement a fast isogeny accelerator architecture that uses fast and par...
On the non-tightness of measurement-based reductions for key encapsulation mechanism in the quantum random oracle model

2019/5/21
Key encapsulation mechanism (KEM) variants of the Fujisaki-Okamoto (FO) transformation (CRYPTO 1999 and Journal of Cryptology 2013) that turn a weakly-secure public-key encryption (PKE) into an IND-CC...

A Simple Key Reuse Attack on LWE and Ring LWE Encryption Schemes as Key Encapsulation Mechanisms (KEMs)
LWE RLWE KEM
2019/3/13
In this paper, we present a simple attack on LWE and Ring LWE encryption schemes used directly as Key Encapsulation Mechanisms (KEMs). This attack could work due to the fact that a key mismatch in a K...
Tighter security proofs for generic key encapsulation mechanism in the quantum random oracle model

quantum random oracle model key encapsulation mechanism explicit rejection
2019/1/26
The recent post-quantum cryptography standardization project launched by NIST increased the interest in generic key encapsulation mechanism (KEM) constructions in the quantum random oracle (QROM). Bas...
In this paper we revisit some of the main aspects of the DAGS Key Encapsulation Mechanism, one of the code-based candidates to NIST's standardization call for the key exchange/encryption functionaliti...
