Telecommunication Network Management

The explsive growth of data networks has brought with it the need for effective network management. Based on this trend and my own interests,During my graduate study I took lots of courses concentrate on the field of communication networks and gained thorough knowledge of both basic network principles and new emerged technology. The knowledge I have learned covers from physical layer all the way up to the application layer, typicall topics include: Internet architecture,  TCP/IP protocol suit,  ethernet,  wired and wireless LAN(Local Area Network),  Wide area network, IP routing,  network device configuration(router, bridge,etc),  LTE, 3G 4G system, VoIP, IPv6   Also, security and privacy is always a big concern when people using the network. I also attend lectures and do labs and projects about network security such as: Network penetration test, threats modeling and risk management, Cryptography, encryption algorithms implementation(for example, implement hash fuction in hardware), SSL, IPSec, firewall, intrution detection,etc.   In most case, networking labs and pentest must be done in Linux environment, so working with linux system such as Redhat, Backtrack 4 is a must. Besides, many useful network software tools are used to analyze the network such as: Ethereal, wireshark, Metasploit framework, nmap, airodump-ng, ssl-strip, Nessus, OpenVas,etc.   I will soon received my graduate certificate in telecommunication network management and I'm currently working on CCNA(Cisco Certified Network Associate), hopefully I will get it in couple of months.

Hardware design with FPGA

Since the first time I used a FPGA  in my design, I gradualy noticed that how FPGAs technology are used in such many different fields and critical applications.  I never stop to learn FPGA design skills and keep practising by doing projects until now. I master the skills in this area which mainly includes: Hardware behavior/structure/logic design using VHDL,  functional and timming simulation using Modelsim,  function verification using Testbench,  DCM(digital clock management),  timming constraint,  embedded  cores and IP cores,  pow analyze,  FPGA device configuration,  on-chip debug using chipscope. Experienced in using Xilinx, Altera FPGA devices and EDA tools includes ISE, Quartus II, Modelsim, Chipscope. Please refer to the project section for information about my previous FPGA design projects.

Bernstein to NIST's SHA-3 competition and has been selected for the second round.I'm currently working on this project to implement and evaluate CubeHash in hardware using Xilinx FPGA. Hopefully, Cubehash may continue to be selected for the next round of the competition. Details about CubeHash please visit the aurthor's website: http://cubehash.cr.yp.to/

*Design of grain stream cipher algorithm on FPGA                                  (NYU-poly) 11/2009-12/2009

The Grain stream ciphers are designed to be very small and efficient in hardware.The ciphers use two shift registers, one with linear feedback (LFSR) and one with nonlinear feedback (NFSR). The LFSR provides a large minimum period and good randomness properties. The NFSR adds nonlinearity. The output is generated through a nonlinear filter taking inputs from both shift registers. More details about grain stream cipher are avalable at http://www.it.lth.se/grain/

I successfully implement the grain cipher in  Xilinx Spartan3E-250 FPGA. I Complete the entire VHDL coding as well as a user interface using LED display and buttons. The outcome was show in testbed, please see the picture at my "Project Showcase" part:click here:Grain stream cipher hardware implementation

Use MSComm control which based on Visual Basic 6.0 to achieve the serial communication between PC and digital camera. The system functions well for remote monitoring the water production at Baoji Water Supply Company so far.

*Intelligent Tracking Robot                                                                              (Wuhan) 2007 summer

In order to participate a small robot competition in my colledge, I took my first opportunity  to design an entire control system when I was a rising sophomore. I used photoelectric sensors, proximity switches and hall sensors to detect road conditions and speed. I also coded the single chip to receive the detection circuit’s signal and give orders to the DC motor drive circuit, in order to control and adjust the robot’s position. It was a huge encouragement when my first showing of a control system by a single chip coupled with digital and analogue circuits went well.
