Message Integrity in the World Wide Web: Use of Nested Hash Function and a Fast Stream Cipher

Sheena Mathew, K. Paulose Jacob
2006 2006 International Conference on Advanced Computing and Communications  
The focus of this work is to provide authentication and confidentiality of messages in a swift and cost effective manner to suit the fast growing Internet applications. A nested hash function with lower computational and storage demands is designed with a view to providing authentication as also to encrypt the message as well as the hash code using a fast stream cipher MAJE4 with a variable key size of 128-bit or 256-bit for achieving confidentiality. Both nested Hash function and MAJE4 stream
