Challengeable Secured Message Authentication
In the message passing concept security is primarily important in the world and also receiver should believe that receiving message is true and sent by valid source. The authors' aim focuses on providing challengeable security without using any keys in sender and receiver sides and to fulfill the receiver faith. Vandermonde and GF n are the two significant process involves in the encoding and decoding techniques. In this paper, they use these techniques to achieve the greater extent security in message passing concept. Here they are using GF n logarithmic operations instead of normal arithmetic operations. In their paper, they propose architecture of message passing and they examine the issues of data security.
