An encrypted data-transportation method for distributed system

Abstract

To improve the data security level of the distributed simulation system, propose an encrypted transportation method based on Chaos Theory. The method separates the data in simulation system into two categories, the simulating data and the file data. The simulating data are encrypted real time by the direct Logistic-based encryption algorithm, while the file data are encrypted by the mixed logistic encryption algorithm. The method can provide the high security level for the distributed simulation system. The Chaos Key in these algorithms is generated by Logistic mapping. The Key is updated automatically via Chaos iteration during simulation advanced. The synchronization of the encrypted key is achieved via the system time synchronization and the same initial Chaos conditions. This encrypted method has its utility value and been proved feasible and efficient. © 2011 Springer-Verlag.
