| Abstract | ||
| In this work , a novel approach is used to send messages on unreliable channel from the transmitter to the receiver. The message is divided into packets(8 characters length), every packet has two indexes and content. The indices refer to the number of copies of the package and package number. The packet contents is reversed its order and put in a buffer. A complex encrypted method based on ordinary Petri nets, Binary Code Decimal(BCD), ones complement and two complement coding , is used to encrypt each character in a nonlinear manner. Two ordinary Petri Nets models are used one for the sender(encryption) and the other for the receiver(decryption). The sender and receiver are comminuted with each other using colored Petri nets and high level language to protect their packets from intrusions and lost on the unreliable channel | ||
