IMPLEMENTATION OF ADVANCED ENCRYPTION STANDARD (AES) FOR HIGH-SECURITY APPLICATIONS

Advanced encryption standard is a steganographic algorithm that will be used to protect the confidential data. In this project we use a Symmetric key, i.e. same key expansion algorithm is used for both encryption and decryption. The AES can be programmed in software or built in with hardware implementations (like FPGA). The numbers of rounds that has to be performed depends on the size of the key. As we are using 128-bit key which consists of 10 rounds, this makes more complex to crack the information. As the key size increases, the number of rounds also increases and complexity also increase. So, it plays a major role in high-security applications. This algorithm is used in many high-security applications like Secure socket layer, OFTP, HTTPS, FTPS, SFTP, AS2, WebDAV, Online financial Transactions, E-Business Code.
