The information safety can be obtained by applying suitable and advanced cryptographic algorithm. This paper simulates the installation and implementation of cryptographic algorithm on a FPGA using Isim software from Xilinx. The result shows that the implementation of 128-bit Advanced Encryption Standard-AES improved considerably the operating speed by 565000 ps for both encryption and decryption process. Similarly, the 233-bit multitive algorithm kP on elliptic curve also enhanced then operating speed at 467661900000 ps. Using above mentioned algorithm, the system maintains the security level meanwhile it does not require very high hardware configuration. Keywords: Information safety, RFID, FPGA, AES, point multitive algorithm. 1. Introduction RFID (Radio Frequency Identification) is a technology which uses electromagnetic to identify target. This technology allows object identification through radio transceiver, from which each target could be traced individually. RFID utilizes a tag and a reader to automatically recognize the object based on distant data storage. The working mechanism of RFID system is based on the electromagnetic communication, such as electromagnetic transformation between the transponder and the reader. The antenna of the reader creates an electromagnetic field .
