On the Failure of the Smart Approach of the GPT Cryptosystem

This work addresses a critical vulnerability in a cryptosystem, which is significant for cryptography researchers and practitioners, though it appears incremental as it focuses on breaking a specific variant.

The authors tackled the security of the GPT cryptosystem by developing a new algorithm that breaks its smart approach, demonstrating that puncturing the public code and applying the Frobenius operator enables the construction of an alternative secret key.
