The high processing bit rate of a high performance cryptosystem for of video encryption/decryption is the result of video streaming application. Our proposed the high speed of encryption/decryption of system is the combination of two the symmetric key algorithm. The cryptographic algorithms, symmetric key video decoder is also integrated into this algorithm and asymmetric key algorithm system to test the functionality of the (also called public key algorithm) to take proposed cryptosystem. This system is their benefits. The symmetric key algorithm implemented in Verilog-HDL, simulated by (ZUC) is used to encrypt/decrypt video, and using the ModelSim simulator and evaluated the public key algorithm (RSA) performs the by using Altera Stratix IV-based encryption/ decryption for the secret key. Development Kit. The speed of video This architecture has high performance, decryption achieves up to Gbps at the including high security and high processing operating frequency of 125 MHz, which bit rate. High security is achieved due to the satisfies applications with high bandwidth ease of key distribution of the asymmetric requirement such as video streaming. key cryptosystem and the secret key can be Keywords: cryptosystem, encryption, decryption, RSA, ZUC, FPGA. INTRODUCTION Nowadays information security is a subject with a high interest. The development of computer networks, particularly the Internet, results more and more applications and services are carried out electronically, for example, PayTV, video streaming, internet-banking, and so Trang 200 on. Since the information on .
