course

Since 2004 I have taught various classes for undergraduate and graduate students, They are including

• system programming

• computer networks

• introduction to security

• data structures

• capstone design (for SCSC)

• problems solving in JAVA (for SCSC)

• security issues in big data (for graduate students)

introduction to security

This course covers a general introduction to security explaining in two parts. One is cryptography and the other is network security.

This course intends to undergraduate students for junior and above. Students are expected to have solid backgrounds of one of programming languages in C, C++ or Java. Class computer networks is recommended but not required.

Main topics covers in the class are

• Cryptography

• Transport layer security (TLS)

• Wireless network (Wi-Fi) security

• Web security

At the end of the course, students should be able to explain various kinds of ciphers and to implement those ciphers in different languages. Also, students can design a security protocol for networks learning from TLS and DNS. Further, student will learn notorious vulnerabilities of Web in the past by exceeding those weaknesses in the lab.

system programming

The course focuses on a lower-level language, the 64-bit assembly language and its implementations to understand better for the x86 architecture.

This course intends to undergraduate students for sophomore. Students must have solid backgrounds of the C language.

Main topics covers in the class are

• Binary representation of data in the system

• Assembly language of x86 in the 64 bits

• Optimization of C language based on the assembly language

At the end of the course, students should be able to write C code in the optimized way.

computer networks

This course covers routing protocols and reliable transportation of data in the Internet.

This course intends to undergraduate students for junior and above. Students are expected to have solid backgrounds of one of programming languages in C, C++ or Java.

Main topics covers in the class include

• Internet Protocol (IP) version 4 and version 6

• Routing protocols: RIP, OSPF and BGP

• Transportation protocols: TCP and UDP

• Control mechanisms in TCP

• Applications such as HTTP and HTTP3

Students after taking this course should be able to explain how packets are delivered from a source to a destination in Internet with speed and reliability. Student will experience experiments on

• Wireshark

• Socket programming in designated programming language
