information security principles and practice

Chapter fourth Processor Architecture section Y86 instruction set architecture One, programmer visible State 1. Meaning:Each instruction will read or modify portions of the processor state2. "Programmer":It can be the person who writes the program with the assembler code, or the compiler that produces the machine-level code.3. Specific processor status: similar to IA32 There are 8 program registers ,%EAX,%ECX,%EDX,%EBX,%ESI,%EDI,%ESP,%EBP Each program register of the processor store

developed, it uses the cross-compilation, assembly, and connection tools on the host to form an executable binary code and then downloads the executable to run on the target machine. Debugging a lot of methods, you can use the serial port, Ethernet port, etc., the specific use of which debugging method can be based on the target processor to provide support to make a choice. Four, the difficulty of the experiment process 1.arm machine can not connect the XP system properlyJust started to connec

The representation and processing of the information in the 2nd Chapter(i), three kinds of important digital representationsUnsigned number: The encoding is based on the traditional binary notation (numbers greater than or equal to zero).Complement: Encoding is the most common way to represent signed integers (numbers that are positive or negative).Floating-point number: The encoding is a two-base version of the scientific notation for real numbers.Al

, consolidate the previous knowledge, master the method of configuring the environment variables, overall, the experiment is relatively smooth, but in the completion of half the progress of the time, due to computer power, restart the computer led to the experimental content completely zeroed, Again practice again, delay the experimental process, but this makes us grasp more firmly, we will continue to work hard, more careful to complete the future of

the experiment was completed and the relevant environment variables were well configured, the process was relatively smooth. There is no big problem, but if the experiment instruction book is carefully studied in advance, the experimental results should be better. This semester the basic experiment of information security design is over, in these five experiments, our team to solve problems and the ability

-feeling bad, read a lot of confusion, code execution is also less. This week's code package gives me a good chance to practice understanding! So I just took the code out of the video in handy. The feeling learned a lot of content. In particular, the function of fork such functions are in the execution of the code to feel its principle. It was really touching when I finished it!!!Because there is also a recent project of this course, the internet also

after the information is displayed. So we re-established the HyperTerminal, waiting for all the information to be loaded and then input ifconfig, and the result is the same as the experimental instruction Issue: When a shared folder is mounted in HyperTerminal, when communication between the Board and the virtual machine is established, the "Mount-t nfs-o nolock 192.168.0.234:/root/bc/host" command is

In about 04 years, we took the Cryptography technology and principles course one night. The teacher just stood on the podium and said to us happily, "I have just attended an international cryptography academic conference. It is a joke that I have cracked the MD5 algorithm. How can this algorithm be cracked." At that time, we also made it a joke. However, it turns out that this is not a joke, that is, Wang Xiaoyun cracked MD5 at the time. In this case,

any timing or control. This is a reasonable assumption for smaller memory (such as a register file), and for larger circuits, a special clock circuit can be used to simulate this effect. Since instruction memory is used only for reading instructions, we can consider this unit as a combinatorial logic.4 Implementation of the SEQ phaseThe register file has four ports, it supports simultaneous two reads (on ports A and B) and two writes (on Ports E and M). Each port has an address connection and a

learning method is not right, who can not eat a fat, can chew, I too much pursuit of every knowledge point in depth can only lead to any can not learn, pay a lot of time instead of working hard.Vii. Lack ofStudy time does not feel, but examination and do homework time will feel, their study or some flow on the surface, too rough, a lot of things do not notice when reading a book, or think that it is not important to ignore, in fact, are not should, and sometimes need to go through the book repe
