Project Idea :
The main objective of the project entitled” Data Security for Network “ is to provide security for a data for network.
The objectives of data security are to prevent eavesdropping to get access of data and in case are stolen make it difficult to understand the stolen data. These objectives are met through different approaches of data security.
Steganographic techniques are useful to convey hidden information by using various types of typically transmitted text data as cover for concealed communication. Data Security for Network is a data-hiding/hidden-communication method that uses digital imagery as a cover signal.
The present project deals with design and Implementation of Data Security over corporate network using IDEA algorithm for image encryption with cryptography. The image encryption is incorporated into the compression algorithm for transmission over a data network.
Cryptography is a method of mathematical encoding used to transform messages into an unreadable format in and effort to maintain confidentiality of data.
In corporate network of clients/server need to interact with each other and parallel maintain the confidentially of data. Before transmission of the encrypts it using the IDEA algorithm and is then sent on the network. The receiver before reading the file needs to decrypt it using the same algorithm to get the actual data. The keys needed to encrypt/decrypt data are pre-known to specific sender and receiver.
