According to the statement, which made the company Intel, viruses, spyware software, and all kinds of malicious software in general, any threat to computer security will remain in the past. To behave revolution in the field of computer security leader IT industry plans with the help of its new platform TXT (Trusted Execution Technology, the trusted technology implementation), formerly known as LaGrande. We already have a long opportunity to observe technology NX bit protecting certain areas of memory execution code that ideally protects the computer from certain malicious viruses. TXT is a completely new concept of security computer hardware level, including work with virtual PC (of course, with the support of technology virutalizatsii Intel VT).

Technology TXT consists of successive phases of secure information processing and is based on the improved TPM module. The system is the safe execution of program code. Each application running in protected mode, has exclusive access to the resources of the computer, and in the isolated environment will not be able to intervene in any other application. Resources for work in protected mode physically allocated processor and a set of system logic. Safe storage of encryption means using all of the same TPM. Any TPM Encrypted data can be downloaded from the carrier only with the help of the same module that carried out the encryption.

Intel has also developed a system of safe data entry. U malware will not be able to trace the flow of data on the computer logging, and get back only senseless set of characters, as all entry procedures (including transfer of USB, and even mouse clicks) will be encrypted. Protected mode applications can send data to any graphics frame buffer graphics card is only in an encrypted form, thus, malicious code will not be able to make a screenshot and send him a hacker. In addition, encrypted can be only part of the information - for example, a given message window, which will remain for all other applications simply invisible. The protection provided to the kernel and operating system that is loaded into the memory of a special isolated area.

Protecting security at the hardware level - a huge step forward. Even if viruses will not be defeated completely, to maintain the confidentiality of information will be much easier. TXT has built-in self-control, so-called certification, passing TXT components which are checked for integrity, and in the event of failure of one of the tests is not merely a computer display. Work with memory in TXT something similar to the user with a hard disk sections: each processor annex during the launch will devote its isolated section of memory. There are in the system and general, unprotected sections of memory. Thus, TXT covers virtually all computer subsystems

The allocation of memory;

monitoring system events;

Contact chipset and memory;

data storage subsystem;

input device (keyboard and mouse);

withdrawal graphic information.

TXT Development of the technology is now at the finish line. For the first time, it will be applied in 2007 on computers that support vPro platform. In the consumer sector will get TXT only after firmly obosnuetsya among professional systems.
