ABSTRACT

In recent years, fast evaluation of digital data exchange occurs. Because of this protection of information is very vital in data storage and transmission process. Protection of internet banking account passwords, email accounts password etc. needs text protection in digital media. During industrial and research processes, image transmission and storage needs image security in the same way. The National Institute of Standards and Technology (NIST) have taken steps for a process to develop Federal information Processing Standard (FIPS) which should be most flexible, secure, fast and which can replace Data Encryption standard(DES). This new standard is known by name Advanced Encryption Standard (AES). Characteristics of data are depends on its types. Thus same security technique cannot be used for all data types. Similar techniques cannot be used to secure images as well as text from unauthorized access as images have huge data sizes and also has real time constrain problems. However with few changes in method, AES can be used to give security to image as well as text. In this project we have implemented encryption and decryption for text, image, audio and also video using AES.
