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.

Highly Efficient and Light NTRU-Based Key Encapsulation Mechanisms with Small Moduli
MathematicsIn this paper, we present CTRU-Light, an IND-CCA-secure key encapsulation mechanism (KEM) derived from NTRU and RLWE (and RLWR in variant) assumptions over power-of-two cyclotomic rings. Our CTRU-Light employs a compact NTT-compatible modulus q=641 while

FrodoKEM: A CCA-Secure Learning With Errors Key Encapsulation Mechanism [PDF]
IACR Communications in CryptologyLarge-scale quantum computers capable of implementing Shor's algorithm pose a significant threat to the security of the most widely used public-key cryptographic schemes. This risk has motivated substantial efforts by standards bodies and government agencies to identify and standardize quantum-safe cryptographic systems.

Weak-Key Analysis for BIKE Post-Quantum Key Encapsulation Mechanism
IEEE Transactions on Information Forensics and Security, 2023 The evolution of quantum computers poses a serious threat to contemporary public-key encryption (PKE) schemes. To address this impending issue, the National Institute of Standards and Technology (NIST) is currently undertaking the Post-Quantum Cryptography (PQC) standardization project intending to evaluate and subsequently standardize the suitable PQC

Chosen-Ciphertext Secure Key Encapsulation Mechanism in the Standard Model [PDF]
IEEE Access, 2021 Key Encapsulation Mechanism (KEM) is a foundational cryptography primitive, which can provide secure symmetric cryptographic key material for transmission by using public key algorithms. Until now, many Chosen-Ciphertext (IND-CCA) secure KEM schemes are constructed from Chosen-Plaintext (IND-CPA) or One-Way (OW-CPA) secure PKE via the generic Fujisaki ...

Attack on the Edon-kKey Encapsulation Mechanism [PDF]
2018 IEEE International Symposium on Information Theory (ISIT), 2018 The key encapsulation mechanism Edon-K was proposed in response to the call for post-quantum cryptography standardization issued by the National Institute of Standards and Technologies (NIST). This scheme is inspired by the McEliece scheme but uses another family of codes defined over $\mathbb{F}_{2^{128}}$ instead of $\mathbb{F}_2$ and is not based on

Implementation of a leakage-resilient ElGamal key encapsulation mechanism [PDF]
Journal of Cryptographic Engineering, 2016 Leakage-resilient cryptography aims to extend the rigorous guarantees achieved through the provable security paradigm to physical implementations. The constructions designed on basis of this new approach inevitably suffer from an Achilles heel: a bounded leakage assumption is needed.

Plaintext Awareness in Identity-Based Key Encapsulation∗† [PDF]
, 2013 The notion of plaintext awareness (PA) has many applications in public key cryptography: it offers unique, stand-alone security guarantees for public key encryption schemes, has been used as a sufficient condition for proving indistinguishability against
