Abstract
Interprocess communication (IPC) is the interface for communication between different programs. Communication occurs through message transfer. We gave a model for security of these messages. We applied XOR cipher and AES cipher on these methods and checked their credibility. Same size for message and key was used to make it difficult finding key that is traveling with the encrypted message. Moreover, we proposed a method to deal with DDoS attacks and save the system from going offline. At the end we tested our system on basis of speed, security and integration with the system. As a result, we got state-of-the-art system on basis of security.
