Abstract
Satellite image Security is playing a vital role in the field of communication system and Internet. This work is interested in securing transmission of Meteosat images on the Internet, in public or local networks. To enhance the security of Meteosat transmission in network communication, a hybrid encryption algorithm based on Advanced Encryption Standard (AES) and Rivest Shamir Adleman (RSA) algorithms is proposed. AES algorithm is used for data transmission because of its higher efficiency in block encryption and RSA algorithm is used for the encryption of the key of the AES because of its management advantages in key cipher. Our encryption system generates a unique password every new session of encryption. Cryptanalysis and various experiments have been carried out and the results were reported in this paper, which demonstrate the feasibility and flexibility of the proposed scheme.
Highlights
The amount of satellite image has increased rapidly on the Internet, in public or local networks
Meteosat image security becomes increasingly important for many applications, e.g., confidential transmission, multispectral imaging for providing electronic images of clouds, land and sea surfaces, analysis of air masses to monitor the thermodynamic state in the lower part of the atmosphere and environment data collection and relay transmitted by automatic platforms[1]
The unlawful, unofficial, and unauthorized access and illegal use of Meteosat imagery increases the importance of information security to keep the critical and confidential imagery and transmission process secure, dependable, trustworthy, and reliable
Summary
The amount of satellite image has increased rapidly on the Internet, in public or local networks. We find, the public symmetric AES algorithm, which has proven its robustness against different types of attacks nowadays [4,5,6,7,8,9], the asymmetric RSA [10,11,12] algorithm and the IDEA algorithm. Using these algorithms allow separately kind of luxurious ensure confidentiality. For this reason, a hybrid cryptosystem based on both AES and RSA is proposed.
