A Code-specific Conservative Model for the Failure Rate of Bit-flipping Decoding of LDPC Codes with Cryptographic Applications
Paolo Santini, Alessandro Barenghi, Gerardo Pelosi +2
Characterizing the decoding failure rate of iteratively decoded Low- and Moderate-Density Parity Check (LDPC/MDPC) codes is paramount to build cryptosystems based on them, able to…
Security analysis of a blockchain-based protocol for the certification of academic credentials
Marco Baldi, Franco Chiaraluce, Migelan Kodra +1
We consider a blockchain-based protocol for the certification of academic credentials named Blockcerts, which is currently used worldwide for validating digital certificates of com…
Analysis of the error correction capability of LDPC and MDPC codes under parallel bit-flipping decoding and application to cryptography
Paolo Santini, Massimo Battaglioni, Marco Baldi +1
Iterative decoders used for decoding low-density parity-check (LDPC) and moderate-density parity-check (MDPC) codes are not characterized by a deterministic decoding radius and the…
Analysis of reaction and timing attacks against cryptosystems based on sparse parity-check codes
Paolo Santini, Massimo Battaglioni, Franco Chiaraluce +1
In this paper we study reaction and timing attacks against cryptosystems based on sparse parity-check codes, which encompass low-density parity-check (LDPC) codes and moderate-dens…
Efficient Search and Elimination of Harmful Objects in Optimized QC SC-LDPC Codes
Massimo Battaglioni, Franco Chiaraluce, Marco Baldi +1
The error correction performance of low-density parity-check (LDPC) codes under iterative message-passing decoding is degraded by the presence of certain harmful objects existing i…
Cryptanalysis of a One-Time Code-Based Digital Signature Scheme
Paolo Santini, Marco Baldi, Franco Chiaraluce
We consider a one-time digital signature scheme recently proposed by Persichetti and show that a successful key recovery attack can be mounted with limited complexity. The attack w…
