Plaintext awareness in identity-based key encapsulation [PDF]
International Journal of Information Security, 2013 The notion of plaintext awareness ( $${\mathsf{PA}}$$ 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 adaptive chosen-ciphertext attacks ( $${\mathsf{IND}\hbox {-}{\mathsf{CCA ...

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

Randomized Key Encapsulation/Consolidation
CoRRThis article bridges the gap between two topics used in sharing an encryption key: (i) Key Consolidation, i.e., extracting two identical strings of bits from two information sources with similarities (common randomness). (ii) Quantum-safe Key Encapsulation by incorporating randomness in Public/Private Key pairs. In the context of Key Consolidation, the

Standard Lattice-Based Key Encapsulation on Embedded Devices [PDF]
Transactions on Cryptographic Hardware and Embedded Systems, 2018 Lattice-based cryptography is one of the most promising candidates being considered to replace current public-key systems in the era of quantum computing. In 2016, Bos et al.

Lossy Key Encapsulation Mechanism and Its Applications
, 2017 We introduce a new notion, lossy key encapsulation mechanism lossy KEM, which enhances the notion of key encapsulation mechanism with lossiness, and can be more efficient than lossy trapdoor functions. We show that lossy KEM can be constructed from lossy trapdoor functions, lossy trapdoor relations, and entropic projective hashing. Using lossy KEM as a

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

Homomorphic-Policy Attribute-Based Key Encapsulation Mechanisms [PDF]
, 2016 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 ...
