With the increasing deployment of telecommunications networks, securing data information has led to the adoption of various encryption methods to protect against different types of attacks. Numerous encryption algorithms have been developed to meet security criteria such as confidentiality, data integrity, and prevention of unauthorized data access. Given the utilization of data contained in satellite images, it is crucial to employ and adapt these security techniques to such data types.In this context, a cryptosystem for encrypting InSAR interferograms is proposed, based on the Advanced Encryption Standard (AES) algorithm with a 256-bit key generated by a GEFFE generator. The encryption mode used is Output Feedback (OFB). The encrypted InSAR image undergoes mixing with a logistic map to model chaotic behavior. The results provided by the cryptosystem, as assessed through objective and statistical evaluations, are considered satisfactory and acceptable.

摘要

With the increasing deployment of telecommunications networks, securing data information has led to the adoption of various encryption methods to protect against different types of attacks. Numerous encryption algorithms have been developed to meet security criteria such as confidentiality, data integrity, and prevention of unauthorized data access. Given the utilization of data contained in satellite images, it is crucial to employ and adapt these security techniques to such data types.In this context, a cryptosystem for encrypting InSAR interferograms is proposed, based on the Advanced Encryption Standard (AES) algorithm with a 256-bit key generated by a GEFFE generator. The encryption mode used is Output Feedback (OFB). The encrypted InSAR image undergoes mixing with a logistic map to model chaotic behavior. The results provided by the cryptosystem, as assessed through objective and statistical evaluations, are considered satisfactory and acceptable.
