Fortified Encryption: Integrating Confidentiality, Integrity, and Authenticity in Fully Homomorphic Schemes.

Description :

Résumé: This research project examines the creation of a FHE scheme using two homomorphic block cipher schemes: RLHABC and RLHMBC. While RLHABC is additive and RLHMBC is multiplicative, they primarily focus on confidentiality. Through their application in Counter mode with CBC-MAC (CCM) [4], it is possible to incorporate a label for integrity and authenticity. This method builds a secure, efficient FHE framework ensuring confidentiality, integrity, authenticity using RLHABC-CCM and RLHMBC-CCM in a switchable mode [7]. Démarche: Literature Review: • Conduct a state-of-the-art analysis highlighting the various challenges associated with Homomorphic Encryption (HE) especially for IoT environment. • Conduct a thorough analysis of existing HE schemes. Schema Design: • Establish the architecture of the proposed FHE scheme using RLHABC and RLHMBC based on a switchable mode. • Detail the integration of the CCM mode to ensure integrity and authenticity. Implementation: • Create a simulation environment to test homomorphic operations. Security Analysis: • Evaluate the security properties of the proposed scheme. • Conduct a theoretical cryptanalysis to evaluate the new schemas' resistance to common attacks including known plaintext/ciphertext attacks, differential attacks and forgery attacks. Performance Evaluation: • Compare the performance of the proposed scheme against existing homomorphic encryption methods in terms of speed, and resource utilization, and cipher-text sizes. Case Studies: • Present real-world scenarios or case studies where the new method is applied, demonstrating its practicability. Documentation and Presentation: • Compile findings into a comprehensive thesis; present and publish research.
