A SURVEY ON ENHANCE SECURITY USING AES WITH MULTIPLE CHAOTIC MAPS

Abstract

Geographic Information System contains Geospatial data which is related to space or Earth surface related
data.GIS data is used in many fields like military aspects, satellite sensor Technologies, Government Organizations,
Disaster Defence, Public Security, etc. GIS Images or Satellite images contains huge data about some particular area &
spatial database is totally depend on the Geological Image. GIS data contains such confidential information which must
be kept away from unauthorized user. So Geospatial data i.e GIS Images requires more Security policies against
unauthorized user. Here in this report such security policies for Geospatial data are discussed. Here we discuss some
techniques of encryption on Geological images such as AES algorithm. Chaotic Series and logistic Maps are used to
perform Encryption and Decryption operation with composition with AES algorithm. The encrypted cipher images
always display the uniformly distributed RGB pixels. Uniform histogram of encrypted image shows high security of data.
