Abstract :

The Rapid Advancement Of Digital Healthcare Technologies And Telemedicine Systems Has Significantly Increased The Need For Secure Transmission And Storage Of Medical Images. Protecting Sensitive Patient Information From Unauthorized Access, Tampering, And Data Breaches Has Become A Major Challenge In Modern Healthcare Environments. This Paper Presents An Efficient And Secure Medical Image Encryption Framework Based On Reversible Logic Cryptography Design (RLCD). The Proposed Architecture Integrates Linear Feedback Shift Registers (LFSRs) And XOR-based Encryption Mechanisms With Reversible Logic Gates To Achieve High-speed, Low-power, And Lossless Cryptographic Operations. Reversible Logic Minimizes Energy Dissipation By Reducing Information Loss During Computation, Thereby Improving Hardware Efficiency And Supporting Sustainable Cryptographic System Design. The Proposed Framework Ensures Secure Encryption And Accurate Decryption Of Medical Images While Preserving Image Integrity And Diagnostic Quality, Which Are Critical Requirements In Healthcare Applications. The Complete System Is Implemented Using Verilog Hardware Description Language (HDL), Enabling Efficient Simulation, Synthesis, And Hardware Realization For FPGA And VLSI Platforms. Experimental And Performance Analysis Results Demonstrate That The Proposed RLCD-based Cryptographic Framework Achieves Improved Security, Reduced Power Consumption, Optimized Hardware Utilization, And Faster Processing Speed Compared With Conventional Encryption Approaches. Hence, The Proposed System Provides A Reliable And Energy-efficient Solution For Secure Medical Image Management In Modern Healthcare Systems.
