TLDR
The proposed constructions are the first of its kind under coding-based assumption in the standard model that do not use the \(\kappa \)-repetition paradigm initiated by Rosen and Segev at Theory of Cryptography Conference (TCC), 2009.Abstract:
In this paper, we propose an IND-CCA2 secure Key-Encapsulation (KEM) in the standard model using the Niederreiter Encryption scheme. Also, we propose a PRIV-1CCA secure deterministic variant of the Niederreiter encryption scheme in the standard model. The security of these constructions are reduced to the hardness of the Syndrome Decoding problem and the Goppa Code Distinguishability problem. To the best of our knowledge, the proposed constructions are the first of its kind under coding-based assumption in the standard model that do not use the \(\kappa \)-repetition paradigm initiated by Rosen and Segev at Theory of Cryptography Conference (TCC), 2009.read more

Secure hybrid encryption from weakened key encapsulation
Dennis Hofheinz,Eike Kiltz +1 more
TL;DR: Constrained chosen-ciphertext security is a new security notion for KEMs that has a very constructive appeal and is demonstrated with a new encryption scheme whose security relies on a class of intractability assumptions strictly weaker than the Decision Diffie-Hellman assumption.

TL;DR: This paper discusses Cryptography in the Multi-string Model, Secure Identification and QKD in the Bounded-Quantum-Storage Model, and a Tight High-Order Entropic Quantum Uncertainty Relation with Applications.

Lossy Trapdoor Functions and Their Applications.
Chris Peikert,Brent Waters +1 more
TL;DR: In this paper, a general cryptographic primitive called lossy trapdoor functions (lossy TDFs) is proposed, which can be used for constructing several important cryptographic tools, including (injective) trapdoor function, collision-resistant hash functions, oblivious transfer, and chosen ciphertext-secure cryptosystems.
