An efficient SEAC system for different data transmission over internet
Shaikh Nasreen, Suchita Wankhede · 2016
Data transmission in a secure manner over the internet has gained higher interest since last decade as the use of encryption for transmitting embedded files before compression is very essential. The major challenge is designing the architecture so as to perform the file encryption at sender side and the file compression at the NSP side in order to achieve the distinguished works assigned to senders and NSP. The proposed architecture comprises a novel architecture where resources required for file compression are utilised from NSP quota while resources only for encryption are used from Sender quota. The proposed system makes use of pre-defined AES encryption algorithm for encrypting the files and LSB Steganography for hiding the sensitive data in the images. With the AES, arithmetic methodology is more productive for better compression of images that are been already encrypted. While as far as compression is concerned, Huffman algorithm is not so suitable, as it gives less compression proportion, than the advanced lossless coders of image which takes input as, intrinsic or decoded images.
