Light-Weight Energy Efficient Encryption Scheme for Vehicular Ad Hoc Network

Vehicular Ad Hoc Networks are a one form of wireless networks in which Road Side Units (RSU) and vehicles are the communicating nodes, providing each other with information such as traffic information and safety warning. They are self-distributed and organized. They can be useful in avoiding accidents and traffic congestion. Providing safety and comfort applications such as information about road block, fuel station, and traffic are main purposes of the VANET. VANETs are highly dynamic and energy constraint in nature, Due to this nature of VANET it is more challenging to achieve the security. Security and energy consumption are important issues in VANET. Previously data confidentiality can be achieved by AES algorithm in VANETs. But AES requires more energy for the process of encryption and decryption. This paper introduces A Light-Weight Energy Efficient Encryption Scheme for achieving security in energy efficient way. Transmission of data is not the only source of energy consumption there are many much like encryption and decryption. Light-Weight Energy Efficient Encryption scheme saves the energy in the process of encryption/decryption of data.
