Abstract

Global command and control system (GCCS-Joint) is a command, control, communications, computers and intelligence (C4I) system which consists of hardware, software, procedures and standards and which provides directory services, enterprise services and security services by exchanging imagery, intelligence, status of forces and planning information. In order to secure this exchange of imagery and information, we need more secure techniques and algorithms to be implemented. During the war, the commanders and forces needs the information and images of the exact location to which they are going to target and these images can be easily taken from the satellite. But the main problem of these satellite images is its transmission over the unsecure electronic media. This paper basically introduces a technique for the encryption and decryption of satellite imagery in order to securely transmit it during the war. The methodology used here for the process of encryption and decryption is that of chaotic maps. The research work is carried out by using the Henon and logistic maps.

 

Key words: Global command and control system (GCCS-Joint), security, satellite imagery, encryption, decryption.
