CCA2 Attack and Modification of Huang<i>et al</i>.’s Public Key Encryption with Authorized Equality Test

2016 · The Computer Journal

In this article, we identify a flaw in Huang et al.'s public key encryption with authorized equality test (The Computer Journal, 2015). More precisely, we point out that the proof of the indistinguishability under adaptive …

An Analysis of Blockchain Consistency in Asynchronous Networks: Deriving a Neat Bound

2019 · arXiv (Cornell University)

Formal analyses of blockchain protocols have received much attention recently. Consistency results of Nakamoto's blockchain protocol are often expressed in a quantity $c$, which denotes the expected number of network delays before some block is …

Optimized Polynomial Multiplier Over Commutative Rings on FPGAs: A Case Study on BIKE

2019

In this paper, we present two constant-time FPGA-based polynomial multipliers for post-quantum secure key encapsulation mechanisms based on quasi-cyclic codes, which are among round 2 candidates in the NIST PQC standardization process. The pipelined hardware …
