Distinguishers for Skew and Linearized Reed-Solomon Codes

Researchers have proven that generalized skew and linearized Reed-Solomon (GSRS and GLRS) codes can be efficiently distinguished from random codes using a square code method, undermining their security promise in cryptographic systems. This matters to developers because it reveals vulnerabilities in these coding schemes, which were thought to offer enhanced security with smaller key sizes compared to other methods like Classic McEliece. Developers should watch for further research on secure alternatives or improvements to current coding techniques.
