Abstract :
Wearable devices for biomedical instrumentation could generate the medical data and transmit to a repository on cloud service through wireless networks. In this process, the private medical data will be disclosed by man in the middle attack. Thus, the archived data for healthcare services would be protected by non-standardized security policy by healthcare service provider (HSP) because HIPAA only defines the security rules. In this paper, we adopted the Advanced Encryption Standard (AES) for security framework on wearable devices, so healthcare applications using this framework could support the confidentiality easily. The framework developed as dynamic loadable module targeted for lightweight microcontroller such as msp430 within embedded operating system. The performance was shown that the module can support the real-time encryption using electrocardiogram and photoplethysmogram. In this regard, the processing load for enabling security is distributed to wearable devices, and the customized data protection method could be composed by HSP for a trusted healthcare service.
