A Homomorphic Digit Fragmentation Encryption Scheme Based on the Polynomial Reconstruction Problem

In the fast moving field of computer cryptography, researchers are actively working on addressing various emerging challenges to keep tomorrow’s systems secure. Many efforts are focused on addressing the computation speed and the massive data size requirements of today’s systems. Significant research efforts are targeting the computational complexity by focusing on the number of cryptographic operations or the scope of application. In this paper, we present an asymmetric homomorphic encryption scheme that relies on converting base numbers to a given base in such a way that Leveled Fully Homomorphic Encryption (LFHE) is performed. This lightweight technique is easy to implement and applicable in many fields, especially those that require high speed and safety.
