Design of Chaotic Block Cipher Operation Mode for Intelligent Transportation Systems

Abstract : Information security is a vital aspect of Intelligent Transportation Systems (ITS) involving public data collection. Road images captured for use as a basis of traffic manipulation in ITS should take all precautions for encrypting the wirelessly transferred image. This paper presents an Enhanced Cipher Block Chaining (ECBC) operation mode to ensure optimal cryptographic properties in a block cipher image encryption scheme. ECBC is based on the Cipher Block Chaining (CBC) operation mode and uses chaos based initialization vectors. Results show ECBC yields better information entropy and correlation coefficients than CBC.

 EXISTING SYSTEM :

 ? Intelligent Transportation Systems are a vital part of the evolution toward smart cities. These systems involve many forms of data collection transmitted wirelessly to central servers, which can provide a basis for making real-time decisions for highway traffic ? Common block cipher modes utilize randomly generated initialization vectors in order to make distinct encrypted blocks. However, if the random initialization vectors are poor, patterns emerge that break the encryption scheme. .

 DISADVANTAGE :

 ? A lot of issue has been occurred to the block chain concept since its parent production. ? The problem of providing ITS security can be mapped into the problem of how to reliably distribute communicate with participants.

 PROPOSED SYSTEM :

 • We propose a key management scheme for vehicular communication systems (VCSs). scenario, including the key transfer between two heterogeneous networks and the dynamic key management scheme to decrease the key transfer time. • A novel block chain concept is introduced into the proposed scheme to simplify the key transfer handshake procedure in order to achieve better efficiency . • Secure key management schemes are considered as a critical technique for network security. In this paper, we propose a framework for providing secure key management within the heterogeneous network.

 ADVANTAGE :

 ? Most of the contributions using block chain are devoted to optimize decentralized currency models. ? Basing on the concept of bitcoin, the new crypto currency improves scalability and ?exibility of crypto currencies. ? Despite the fact that there is no other work about using blockchain in VCS, blockchain architectures in some contributions are still valuable for reference.
