Effective Cryptography Mechanism for Enhancing Security in Smart Key System

Our modern technologies are going towards wireless network and communications. Remote Keyless Entry (RKE) system or Smart Key System is an electronic lock used to unlock the vehicle or doors with the help of the wireless key which transmits the fixed code to the receiver. As they are convenient for the modern world, one of the major drawbacks in wireless communications is Security. The RKE wireless system is more vulnerable to attack. The Replay attack is the more commonly occurring attack in RKE system. One of the solution to prevent a replay attack in RKE is Rolling Code. The system is more secure from the attack by the use of an encryption algorithm. We proposed an effective cryptography mechanism to prevent the attack in the smart key system. Our proposed RKE-Crypto model, prevent the replay attack and also reduce the communication attack in RKE system.
