Fault analysis of authenticated encryption systems

Abstract

This project report presents the implementation and analysis of the GIFT cipher, a lightweight symmetric encryption algorithm, using the Python programming language. The GIFT cipher has gained significant attention in the field of cryptography due to its impressive security features and efficient performance. The report begins with an overview of the GIFT cipher's structure and operation, highlighting its key components such as the Substitution-Permutation Network (SPN) and the Feistel-like structure. The Python implementation of the GIFT cipher is discussed in detail, covering the encryption and decryption processes along with the generation of round keys.
