Analysis of common attacks in LDPCC-based public-key cryptosystems

TL;DR

This paper evaluates the security of LDPCC-based public-key cryptosystems against partial knowledge attacks, providing phase diagrams that illustrate the thresholds for successful unauthorized decryption.

Contribution

It introduces a detailed analysis of attack vulnerabilities in LDPCC cryptosystems, including phase diagrams that depict critical partial knowledge levels needed for breach.

Findings

Critical partial knowledge thresholds identified

Phase diagrams illustrate attack success conditions

Security vulnerabilities depend on partial key knowledge

Abstract

We analyze the security and reliability of a recently proposed class of public-key cryptosystems against attacks by unauthorized parties who have acquired partial knowledge of one or more of the private key components and/or of the plaintext. Phase diagrams are presented, showing critical partial knowledge levels required for unauthorized decryption
