Implementation of Block based Data Encryption at Bit - Level

Vol. 11  No. 2  pp. 18-23


With the growth of internet and network, the need for secure data transmission become more and more essential and important, as security is a major concern in the internet world. Data likely to be kept hide from all people except from the authorized user cannot be sent in plane text. So the plane text should be codified i.e. by the process of encryption. Each type of data has its own features, therefore different techniques should be used to protect confidential data from unauthorized access. Here I introduced a new algorithm based on symmetric key block encryption technique. In this algorithm encryption is done on binary file. Since this encryption is done on binary file so this algorithm is applicable for any data such as text as well as multimedia data.
