ENKRIPSI DATA COCKPIT VOICE RECORDER PADA PESAWAT MILITER DENGAN MENGGUNAKAN ALGORITMA SIMETRIS
Abstract
Information confidentiality issues in the military institution is a must, so far the military aircraft should not be equipped with Blackbox as information storage media data plane (FDR, Flight Data Recorder) and information on the cockpit voice (CVR, Cockpit Voice Recorder). On the other hand, the information is needed for the investigation of an accident, but it also Blackbox can be used as guidance in detecting damage of the aircraft systems at the time of treatment. In this thesis was discussed about alternative solutions for problems that are opposite to each other, especially in the media Cockpit Voice Recording (CVR).Solutions offered in this thesis is the application of encryption on the cockpit voice recording systems. The model chosen is encrypted symmetric encryption streamchiper because its strength lies in the confidentiality of password used. After doing some experiments on the type of password that is used, optimal results obtained by applying the password in the form of sound files with audio frequencies.The encryption method became one of the methods chosen for the security of information on the Cockpit Voice Recorder (CVR) with the settings and key generation algorithm will determine the level of encryption security. Information security management system data on the Cockpit Voice Recorder (CVR) military aircraft can be applied in a manner keeping the password to decrypt. Decrypt the voice data is used to determine the cause of the accident and taken as a lesson to improve the safety of military aircraft.References
This study still needs refinement to reproduce the experiment with other types of passwords.
Prototype manufacture was still using audio input sample rate by 8000 and using 16bit resolution, but it still contains noise that needs to be improved quality.
Encryption techniques can be developed in this thesis point by using a more complex encryption.
