摘要

The mobility and open access of wireless communication channels expose sensitive electronic health information to unauthorized access. In Wireless Body Sensor Networks (WBSNs), securing this data is critical. To address these security concerns, the proposed system introduces a Modified-Enhanced Lattice-Based Cryptography with Message Authentication Code (MAC-MELBC) as a hybrid authentication solution. This system integrates both symmetric and asymmetric cryptographic techniques, creating a robust ciphering mechanism. The Message Authentication Code (MAC) ensures message integrity and authentication, while symmetric key cryptography supports efficient key management and validation of communication parties. The MAC-MELBC method employs symmetric cryptography for the authentication process and asymmetric lattice-based cryptography for secure key generation and data verification. The asymmetric component, MELBC, utilizes advanced lattice-based algorithms to generate encryption keys and perform cryptographic operations for verifying physiological data collected from the human body. The system splits plaintext and applies dual encryption for enhanced security and authentication. Its encryption and decryption mechanisms offer strong protection against various security threats within WBSNs. Performance is evaluated using key generation time, encryption/decryption time, memory usage, total execution time, energy consumption, and resilience against attacks. Compared to conventional algorithms like RSA and Elliptic Curve Cryptography (ECC), the proposed MAC-MELBC demonstrates superior performance, achieving a 96% accuracy rate and offering enhanced security and efficiency for WBSN implementations.
