First of all create the nodes in two rings. From ring 1 select source. From ring 2 select destination. Then the source select the data to transfer. Then select the intermediates from ring 1 and ring 2. The source encrypts the data by using the blowfish algorithm. And generate the message authentication code for the selected data. Then transfer the data to the intermediate 1. The data is transferred from intermediate 1 to admin. Admin transfers the data to intermediate 2. Destination receives the data from intermediate 2. The destination node decrypts the data. And checks the integrity of the data by using the message authentication code.
