A Review on RSA-Huffman Hybrid: towards Secure, Compressed and Adaptive Network Data Transmission

Abstract

The RSA-Huffman hybrid model, which combines asymmetric encryption and lossless compression, has become a viable answer to the increasing demands for safe and effective data transfer. The review evaluates the existing RSA-Huffman techniques based on implementation by application domains (cloud, IoT, Mobile etc), the studies were selected and categories based on their implementation domain, performnces metrics of each and the year article was published. It asses their real-world feasibility, security-efficiency trade-offs, and techniques. Results show improved confidentiality (e.g., high NPCR scores) and compression ratios (50–90%), but they also highlight important drawbacks, including inconsistent benchmarking, fidelity degradation in lossy implementations, computational overhead (notable latency spikes), and new vulnerability risks (e.g., quantum threats). Future developments necessitate uniform evaluation procedures, quantum-resistant modifications, and lightweight optimizations to allow for scalable deployment in resource-constrained systems, even though they are successful in particular situations.
