The Power of Power Codes: New Classes of Easy Instances for the Linear Equivalence Problem
This paper identifies new, algebraically weak classes of instances for the Linear Equivalence Problem (LEP) by generalizing techniques from the Permutation Equivalence Problem (PEP) using power codes and Frobenius automorphisms.
Cryptanalysis of a PIR Scheme based on Linear Codes over Rings
This paper presents a cryptanalytic attack demonstrating that a specific code-based Private Information Retrieval (PIR) scheme can be broken, allowing the server to efficiently determine the requested file index.
