Chaos-Based Secure Communications in Biomedical Information Application

Recently, with the rapid development of biomedical information, establishing secure communication and appropriate security services has become necessary to ensure a information exchange process. Therefore, protect privacy confidentiality personal data, in this study, we use chaotic system, Lü system Lorenz-like generate signals apply them encrypt information. In addition, one states design simple proportional-derivative (PD) controller synchronize master-slave systems for decrypting Then, electrocardiography (ECG) electromyography (EMG), measured about 30 s 60 get tens thousands data from subjects at transmitting side (master) send receiving (slave). After receives encrypted it decrypts PD then obtains 1 mV 2 signals. Thus, can be ensured realized.
