Security of Message Passing Based on Grid Environment

Grid computing architecture was defined to be a complete physical layer. The message transfer in network must be in secure. In this study, we propose the encryption algorithm in every grid node to keep information in security. Sender requests key code from receiver grid node, uses this key code to encrypt message to produce cipher text and sends out. Receiver also uses this key code to decrypt cipher text to get original message. This key code is kept in both sides. When these algorithms install in all grid nodes, we can keep message process be secure in the system.
