In this wok, a novel approach based on ordinary Petri net is used to generate private key . The reachability marking of petri net is used as encryption/decryption key to provide more complex key . The same ordinary Petri Nets models are used for the sender(encryption) and the receiver(decryption).The plaintext has been permutated using look-up table ,and XOR-ed with key to generate cipher text
