Abstract
As medical devices become increasingly interconnected through the Internet of Medical Things (IoMT), safeguarding image data against unauthorized access and tampering has become a pressing challenge. Many existing solutions fall short in balancing computational efficiency with robust encryption, particularly when high-fidelity recovery of diagnostic images is required. This work presents SecureNet, a hybrid encryption framework tailored for medical imaging applications. This work proposes SecureNet, a compact and resilient encryption framework designed for secure medical image transmission. SecureNet leverages a convolutional autoencoder to extract compact latent features, applies spatial rearrangement using a Hilbert curve to disrupt pixel locality, and diffusion with a chaos-driven random projection. The result is a highly randomized and distorted representation, complicating any attempt at unauthorized analysis. The encrypted data can be accurately recovered through symmetric decryption operations. Experimental results, supported by security and comparative analyses, validate the effectiveness and generalizability of the proposed framework in resisting various attacks, demonstrating its encryption efficacy and performance on par with state-of-the-art approaches. The framework presents a scalable solution for securing healthcare data in dynamic and resource-constrained IoMT environments.
期刊介绍:
The impact of computers has nowhere been more revolutionary than in electrical engineering. The design, analysis, and operation of electrical and electronic systems are now dominated by computers, a transformation that has been motivated by the natural ease of interface between computers and electrical systems, and the promise of spectacular improvements in speed and efficiency.
Published since 1973, Computers & Electrical Engineering provides rapid publication of topical research into the integration of computer technology and computational techniques with electrical and electronic systems. The journal publishes papers featuring novel implementations of computers and computational techniques in areas like signal and image processing, high-performance computing, parallel processing, and communications. Special attention will be paid to papers describing innovative architectures, algorithms, and software tools.
