Abstract

OBJECTIVES
We have not only examined telemedicine scenario but also applied IPSec(AH, ESP) algorithms under VPN(Virtual Private Network) for performance evaluation of telemedicine system's security and transmission.
METHODS
In this study, we applied IPSec(AH, ESP) algorithms under VPN(Virtual Private Network) protocol when transmit healthcare data through Satellite Network. At that time, we evaluated performance of telemedicine system through RTT(Round Trip Time), Jitter, Bandwidth that indicate to QoS(Quality Of Service).
RESULTS
It is possible to transfer remote healthcare data over Satellite Network under provided image of 15 frame and bio-signal of 10 kbps and RTT(Round Trip Time) of 774.53ms, Jitter of 25.2ms. But applying IPsec(AH, ESP) under VPN(Virtual Private Network), it is frequently happened distortion of image data affected SHA-1 and 3DES algorithm.
CONCLUSION
In this study, it is possible to use telemedicine system for Secure Satellite Network, but demand to be based QoS(Quality Of Service) limited. We expected that it is possible to use the designed system in the disaster area.
