This work proposes the application of Advanced Encryption Standard (AES) algorithm in Universal Asynchronous Receiver Transmitter (UART) module for secure transfer of data. The proposed architecture implements AES-128 algorithm that encrypts the data before transmission through UART transmitter and decrypts after receiving the data at UART receiver module.(More)
This work presents an optimized Substitution Box (S-Box) for Advanced Encryption Standard (AES) design. The S-Box is one of the most important components of AES. During SubByte transformation, the eight bit input is substituted by eight bit output using the S-Box. S-Box is constructed by composing two transformation - multiplicative inverse in Galois Field(More)
Video Watermarking is a very popular and effective way of copyright protection of videos. But in some cases simple watermarking is not enough because security has become a major concern with the rapid development of technology and internet access. Thus, to enhance the security of the embedded watermark, in this paper the watermark is encrypted using a key(More)
