Energy Efficiency Analysis of Post-Quantum Cryptographic Algorithms
IEEE Access, 2021 Classical cryptographic schemes in use today are based on the difficulty of certain number theoretic problems. Security is guaranteed by the fact that the computational work required to break the core mechanisms of these schemes on a conventional ...

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.

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.

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 ...

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
