This paper presents the hardware design
of a high performance cryptosystem for
video streaming application. Our proposed
system is the combination of two
cryptographic algorithms, symmetric key
algorithm and asymmetric key algorithm
(also called public key algorithm) to take
their benefits. The symmetric key algorithm
(ZUC) is used to encrypt/decrypt video, and
the public key algorithm (RSA) performs the
encryption/ decryption for the secret key.
This architecture has high performance,
including high security and high processing
bit rate. High security is achieved due to the
ease of key distribution of the asymmetric
key cryptosystem and the secret key can be
easily changed. The high processing bit rate
of video encryption/decryption is the result of
the high speed of encryption/decryption of
the symmetric key algorithm. The H.264
video decoder is also integrated into this
system to test the functionality of the
proposed cryptosystem. This system is
implemented in Verilog-HDL, simulated by
using the ModelSim simulator and evaluated
by using Altera Stratix IV-based
Development Kit. The speed of video
decryption achieves up to 4.0 Gbps at the
operating frequency of 125 MHz, which
satisfies applications with high bandwidth
requirement such as video streaming.
