Summary
Practical Homomorphic Encryption over the Integers for Secure Computation in the Cloud and its Cryptanalysis
Highlights
Implemented practical methods to validate the theoretical upper bounds of additions and multiplications for HE1 and HE1N encryption schemes.
Developed and successfully executed a cryptographic attack on HE1 and HE1N leveraging the Lattice Reduction Algorithm.
Engineered and optimized the OLA Attack Algorithm in Python, leveraging advanced polynomial optimization techniques, resulting in a 20% increase in cryptanalysis efficiency and a 15% reduction in processing time.
Conducted extensive tests with varying polynomial degrees and entropies to assess attack time, yielding a comprehensive security assessment. Identified a 10% increase in attack time under certain conditions.
