SMC is the abbreviation of Self-modifying code. as its name implies, it is "code self-modification", that is, it can be modified before a piece of code is executed.SMC technology is very popular in the DOS era, because the DOS era is closer to the underlying system. So even the current implementation of SMC technology, assembly code is the most convenient.'The use of this feature of

SummaryThe self modifying code technology encrypts the code or data in executable files to prevent others from using reverse engineering tools (such as some common disassembly tools) the static analysis method of the program only decrypts the code and data when the program is running, so as to run the program and access data normally. Computer viruses usually use SMC technology to dynamically modify executable co
Summary
On Intel-based Mac, the system management controller (SMC) manages many low-layer functions. These functions include:
Respond to power button pressing
Responding to the opening and closing of the screen cover of a portable Mac Monitor
Battery Management
Thermal Energy Management
SMS (Sudden Motion Sensor, emergency Motion Sensor)
Environmental photometric sensing
Keyboard Backlight
State indicator light (SIL) Management

SMC has participated in the formulation of standards for high-quality, standard-based connectivity and Internet access solutions. Its products include Ethernet products, wireless network devices, and SOHO devices. To maintain a leading position in the competition and competitive price, SM
A: Test environment:Operating system:SLES SP1 x86_64The SMC version is:1.4.0Second: The operation steps are as follows1. obtain a higher-level SMC management system with DD or clone2. after opening the new management node, first delete the previous network Udev rules and remove all the hosts added in the SMC, and then restart the system3. according to the actual
A brief introduction of SMC
Prior to Solaris 9, there was virtually no complete management interface for the Sun Soalris operating system, and the only available was admintool. Admintool packages as a collection of software groups, making it easier to manage software. Admintool called the package command. The package commands and Admintool can be used alternately in the management of the software. For example, you can use Admintool to install a softw
Many users who use Macs have encountered a situation where the Mac does not boot. Many people are very worried, because if the equipment over the warranty period may also need to pay maintenance, in fact, we do not worry, if everyone's Mac encountered no boot, battery failure, unable to charge and so on sudden failure, you can try to reset SMC, you can solve the problem. The following small compilation teaches everybody Mac resets the
Let's take a look at the advanced technology in win32asm-SMC (Dangdang ......)!!!
What does SMC mean? Its English name is "Self modifying Code". As the name suggests, it is "self-Modification of code "(?) (Sorry, the younger brother hasn't passed cet6 yet. It can only be translated into this ......)
"Code self-modification "? Wow, it's so advanced! Actually not ......
We know that Win32 applications run in
Misunderstanding of static member class:For the most programmers, comparing to SMC, we are more than familiar with static field. So we could analogously guess how SMC works according to static field ' s feature. That leads to a MISUNDERSTANDING.--SMC is only having one instance.Prove misunderstanding is wrong:We may see how stupid this is and after you think this

Although from the perspective of applications, enterprises have gradually increased their requirements for data, voice, and video fusion from Gigabit to desktop, high prices stop some price-sensitive enterprises. To solve this problem, zhibang technology has launched the New SMC 8024L, a fully gigabit network-managed switch. This product is an intelligent network management switch with a layer-2 wire speed of Gbit/s. Its biggest characteristic is its
Secure multi-party Computing Technology

I,What is secure multi-party computing?
To illustrate what is secure multi-party computing, we will first introduce several examples in real life.

Taking the common SMD Schottky diode SS14 SS24 SS34 as an example, three kinds of pipe difference mainly in the current, there are three kinds of encapsulation: SMA, SMB, SMC.
From the cost and volume, the first choice of the smallest size of the SMA/DO-214AC package, other packages are generally not recommended selection.
From the picture below, these three packages are similar, with different main volumes, as can be seen: SMA

Brief history of self-modified code
Self-modified code has a wide range of uses:
1. It was very difficult to use SMC (self-protection code) to protect applications 10 to 20 years ago, even if it was used to put compiled code into the memory.
2. the emergence of 95/NT In The Middle Of 1990s confused programmers about how to protect applications in the new operating system. I don't know how to port the protection measures to this new version. it is no l
tried it and the result is not correct. I found the source code of this tool. I used the source code for step-by-step debugging and tracked a branch. The author wrote a comment. This is the third-generation firmware encryption method, there is no decryption hope in the Update log. (Original article: Fixed crashes with 3. Generation-No decryption possible -) This is the end of things. It took two days last weekend to get the absolute coordinates of GPS... However, I am not worried about writ
