Generic Side-channel attacks on CCA-secure lattice-based PKE and KEM schemes
Lattice based cryptography side-channel attacks CCA transformation
font style='font-size:12px;'>
2019/8/21
In this article, we demonstrate practical side-channel assisted chosen-ciphertext attacks (CCA) over multiple CCA-secure lattice-based public-key encryption schemes (PKE) and key-encapsulation mechani...

2018/3/12
In 2013, Misoczki, Tillich, Sendrier and Barreto proposed a variant of the McEliece cryptosystem based on quasi-cyclic moderate-density parity-check (QC-MDPC) codes. This proposal uses an iterative bi...
Saber: Module-LWR based key exchange, CPA-secure encryption and CCA-secure KEM
CPA-secure encryption CCA-secure KEM
font style='font-size:12px;'>
2018/3/5
In this paper, we introduce Saber, a package of cryptographic primitives whose security relies on the hardness of the Module Learning With Rounding problem (Mod-LWR). We first describe a secure Diffie...
