Image Encryption and Decryption Using Auto Generated Key
Narendra Kumar Dewangan, Manisha Dewangan · 2011
Internet based communications are evolving at a tremendous rate. Encryption of data has become an important way to protect data resources especially on the Internet, intranet sand extranets. Encryption involves applying special mathematical algorithms and keys to transform digital data into cipher code before they are transmitted and decryption involves the application of mathematical algorithms and keys to get back the original data from cipher code. The goal of security management is to provide authentication of users, and integrity, accuracy and safety of data resources. Moreover, an image-based data requires more effort during encryption and decryption. The model for encryption and decryption of an image using auto generated key which is generated by image.
