Background: The main threatin communication is the unauthorized access of information third party withoutthe knowledge of sender and receiver.Hence the security plays a vital role in data transmission systems.Confidential data like internet banking account passwords and email account passwords needs security in their text data. Data can be text, image, video and audio. Methods: The purpose of this research work is to implement a mechanism to hide information (image) using cryptography. Advanced Encryption Standard (AES) is a type of symmetric cryptography standard which can be used to transfer a block of information securely during transmission. Findings: The idea of this paper is to generate an encrypted image by giving image input to AES encryption system and getting the decrypted image as original image by giving encrypted image as input to the AES decryption system. The input image is given through MATLAB R2012b to ModelSim6.3 and the system simulation and synthesis is done by integrating Model Sim to the Altera DE2 115 board through Quartus II software. Conclusion: The maximum frequency attained from this workis 165.462MHz. Finally image is displayed through an LCD which is connected to the board using Video Graphics Array (VGA) Connector.
