- Abstract
- A security-enhanced search and rescue system is required for military or privacy required operations. In this paper, we propose utilization LTE as search and rescue communication link for helping out the limitation of the capacity of COSPAS SARSAT link in the sense of a number of users at the same time. Also, enhancement of security of the search and rescue system by COSPAS SARSAT and LTE made by using encryption mechanism. We employed encryption algorithm as AES/CFB (Cipher FeedBack) 256bit for COSPAS SARSAT with mode and IV (Initialization Vector) key management by return link message. AES 256 bits for LTE was used for an encryption algorithm with IPSec protocol. Some simulation results from Modeling & Simulation Platform for COSPAS SARSAT with LTE Modem were presented in this paper.
