These days, the security of information has become more vital in data transfer through networks and storages, so everyone knows the importance of data encryption to maintain the confidentiality and privacy of information transmitted across different networks. Image ciphering plays a vital role in avoiding eavesdropping or cracking access to the information that is transferred through networks; therefore, to look after the privacy and security of the information that is transferred on the internet, one of the important methods of security is chosen in this paper, which is “Advanced Encryption Standard”. The Advanced Encryption Standard is chosen in this paper based on the capability of it to secure information and the power of it to immunize information from eavesdropping. A Graphical User Interface (GUI) in Matlab is used as software to implement the Advanced Encryption Standard algorithm and to tests various types of High Definition. This research is focused on experiments on different types of pictures (gray, color and black and white) in high quality and seeing the required time for applying the Advanced Encryption Standard algorithm on these pictures. The results of this paper show the time that is required for ciphering and deciphering different types of pictures.

Reconfigurable cache memory is important to improve the cache performance and reduces the energy consumption. In this paper, a review for previous papers related with reconfigurable cache memory were presented and compared it with our work in which we implemented two dimensional reconfigurable cache memory with exploitation of full amount of cache memory size with different organizations and compare the performance of different cache organizations.
